INFN LASA started an R&D activity dedicated to the development of knowledge needed to understand how to improve SRF cavity performances to reach High Q and High G values to accomplish the sustainability and cost reduction requests, as needed for the future large particle accelerators. This R&D activity, funded by INFN, is also enriched by synergies with other LASA activities as PIP-II low beta cavity production, the participation to ILC Technology Network, and by the LASA experience in SRF cavity industrialization developed during the large-scale production of the Eu-XFEL and the ESS SRF cavities. First results obtained on 1.3 GHz single and multi-cell cavities, and the status of the upgraded LASA infrastructures for Vertical Test are presented and discussed.

The upgrade project of the ALBA Synchrotron Light Source is gaining momentum following the official approval of the required funds at the end of 2025. The design of the magnets for the new ALBA II storage ring began in 2021 with the launch of a comprehensive prototyping program aimed at developing and validating the various magnet types required by the new multi-bend achromat (MBA) lattice. The first prototype magnets became available at the end of 2025 and are currently being characterized at ALBA’s magnetic measurements laboratory to assess their performance against the design specifications, as well as to investigate critical aspects such as magnetic cross-talk and mechanical integration between neighboring magnets. In parallel with prototype fabrication, the magnet designs have continued to evolve to keep pace with the successive refinements of the ALBA II lattice over the past years. The lattice is now approaching its final configuration, and together with the lessons learned from the prototyping campaign, this will enable the completion of the magnet designs during 2026. This contribution presents the current status of the magnet prototyping program and outlines the pathway toward the final magnet designs, emphasizing the main challenges encountered and the technological solutions implemented.

Within the Research Facility 2.0 (RF2.0)* project, one of the objectives is the development of novel permanent-magnet technologies and refurbishment strategies aimed at reducing energy consumption in accelerator facilities. In this context, ALBA, ELYTT, and HZB are jointly developing a tunable quadrupole prototype based on permanent magnets, conceived as a demonstrator for next-generation, energy-efficient magnet systems. The prototype is designed to achieve high-gradient focusing while drastically reducing power consumption relative to conventional electromagnets, eliminating the need for large coils and water cooling. Its compact architecture also eases integration into densely packed storage-ring lattices. Tunability is provided through a hybrid approach combining movable soft-iron elements and small auxiliary coils, offering a wide operational range with minimal energy demand. This contribution presents the electromagnetic and mechanical design of the prototype, the assembly strategy, and the current status of the manufacturing and testing.

ALBA is upgrading its storage ring into a 4th-generation diffraction-limited facility, which demands redesigned vacuum chambers. Most of the 268.8 m ring, divided into 16 arcs, will use OFHC-Cu or CuCrZr to dissipate synchrotron radiation and minimize resistive-wall impedance. To meet the injection-efficiency re-quirements, former 16 mm circular cross-section has been replaced by a rhombic geometry providing a 22 mm hori-zontal aperture, 1.25 mm wall thickness and clearances of 1 mm to the magnet poles. Its structural response shows 13 MPa maximum stress with deformations of 3 µm. A short bellows is foreseen between each pair of BPM blocks to absorb chamber displacements from alignment tolerances and thermal expansions while keeping BPM positions fixed. At dipole positions, antechambers with crotch absorbers manage the radiation heat load, with each arc receiving 20.5 kW of power. The entire ring will be NEG-coated to accelerate conditioning and reach the required pressure of 1×10⁻⁹ mbar at 100 Ah. This contri-bution presents the vacuum system status and the design, fabrication progress of the prototypes.

On July 2, 2025, at Elettra, we began the “Dark Period” (DP): the definitive shutdown of Elettra's Storage Ring (SR) with its auxiliary equipment and most of its beamlines. During the first phase of the DP, we removed the entire SR lattice structure with its associated cabling, piping, and supports. At the same time, the Service Area (SA), where most of the equipment for operating the SR was and will be located, was emptied to allow for infrastructure work and the subsequent installation of new racks and equipment. “On the other side of the wall,” most of the photon beam lines are being reconfigured, upgraded, or installed, which involves several changes to the configuration of the SR tunnel's outer shielding wall. The paper describes the status of DP activities, the difficulties encountered, and the mitigation strategies adopted. Logistics plays an important role in this scenario, organizing the handling, transport, storage, and arrival times of materials, equipment, and instrumentation racks. This flow is bidirectional and includes both what is removed and disposed of and the parts to be installed, with a significant coexistence of old and new material.

Generation of rare isotope beams by means of in-flight separation of nuclear fragments and fission products requires complex optical structures usually comprising multiple separator stages. Large apertur magnets providing maximum acceptance, radiation hard and superconducting are used to separate the reference isotope from the bulk of the primary and secondary heayv ion beam. The pre-separator stages are designed to dump a majority of the secondary beam in a controlled way and are therefore often a challenge for radioprotection, shielding and beam catchers. The complex optics of fragment separators makes use of energy degraders, intermediate focal- and image planes to minimie contamination of the desired isotopes. A comparison of optical designs and magnet technologies will be presented.

This presentation will report on the status of assembling and commissioning of the Cathodes And Radio-frequency Interactions in Extremes (CARIE) C-band high gradient photoinjector test facility and the status of high gradient testing of a 1.6 cell C-band RF photoinjector at Los Alamos National Laboratory (LANL). The construction of CARIE began in October of 2022. CARIE will house a high gradient copper RF photoinjector and other high gradient C-band accelerating structures (e.g., multi-cell cryo-cooled accelerating structures). The 50 MW 5.712 GHz Canon klystron powers the facility. The klystron was installed and conditioned in 2024. The output of the klystron is connected to a circulator that was conditioned to operate for up to 12 MW of power. The WR187 waveguide line brings the power from the circulator into a concrete vault that is rated to provide radiation protection for an electron beam powers up to 20 kW. The first RF injector that was fabricated is made of copper and does not have cathode plugs. This injector is installed at the end of the waveguide line and is under commissioning. High gradient commissioning of the photoinjector will validate operation of the CARIE facility. The status of the facility, the designs of the photoinjector and the beamline, and status of the high-power testing of the injector and other C-band components and cavities will be presented.

The proposed energy upgrade of the Continuous Electron Beam Accelerator Facility (CEBAF) incorporates Fixed-Field Alternating-gradient (FFA) arcs utilizing permanent magnet technology. Given the radiation environment within the CEBAF tunnel enclosure, validating the long-term magnetic stability of these materials is a critical step for the project's technical feasibility. This contribution presents an overview of the ongoing permanent magnet radiation resiliency program at Jefferson Lab. We briefly review the experimental methodology used to monitor demagnetization in situ and summarize the operational experience from the initial data-taking campaign. Furthermore, we discuss the upgrades implemented for the second exposure campaign, currently underway, which aims to refine dose correlation and reduce systematic uncertainties. We report on the general status of the program and the roadmap for certifying permanent magnet optics for the proposed upgrade energies.

The storage ring of the Korea-4GSR (Korea 4th Generation Synchrotron Radiation) facility currently under construction consists of a total of 1184 magnets, of which 792 are large-capacity magnets requiring rated currents of 140A or 280A. To drive these large-capacity magnets, magnet power supplies (MPSs) are required to support parallel operation in order to minimize the number of MPS types, thereby improving maintenance efficiency and reducing manufacturing costs. In addition, to ensure beam stability and low-emittance beam performance, current stability of less than 10 ppm and accuracy of less than 100 ppm under long-term operation are required during the prototype development. This paper presents a storage ring modular magnet power supply (SR Modular MPS) rated at 140A, which is designed in a modular form with master–slave-based parallel operation capability, allowing the rated output current to be expanded up to 280A through two-unit parallel operation. The proposed MPS can supply both 140A and 280A rated currents to large-capacity magnets using a single MPS type, and satisfies the MPS performance requirements over the entire operating range through a compensation method applied based on operating-condition-dependent characteristics. Experimental results demonstrate that the developed SR Modular MPS achieves a stability of 2.28 ppm and an accuracy of 45.79 ppm in single-unit operation, and a stability of 5.1 ppm and an accuracy of 45.88 ppm in parallel operation.

The Facility for Antiproton and Ion Research (FAIR), currently under construction in Darmstadt, Germany, is one of the largest and most technically challenging research infrastructure projects in Europe. The project combines large-scale civil construction, complex accelerator and infrastructure systems, and scientific installations within a highly interconnected international project environment. A key aspect of FAIR is the implementation of numerous international in-kind contributions. Accelerator and experiment components are developed, manufactured, and delivered by partner institutions from different member states. This model supports scientific collaboration, technology transfer, and the shared financing of complex infrastructure components. At the same time, it creates major organizational and technical challenges, since different engineering standards, procurement processes, national regulations, and planning cultures must be coordinated within one common project structure. The experience from FAIR clearly shows that projects of this scale cannot be successfully realized through technical expertise alone. The large number of interdependencies between procurement, installation, commissioning activities, and scientific but also financing and regulatory requirements creates a level of complexity that can no longer be managed without the highest level of professional and integrated project management. Additional constraints and acceptance. In this context, the FAIR Project Management Office (FAIR PMO) developed over the course of the project from a traditional reporting and controlling function into a central integration and coordination organization. Schedule planning, risk and cost management, quality management, international supplier and in-kind coordination, as well as configuration and data management, have been closely connected within one integrated management framework. A particular focus is placed on linking technical planning with risk and forecasting methods. Schedule planning, technical maturity, delivery status, resource availability, and risk developments are continuously consolidated and evaluated together. In addition, probabilistic and holistic risk and schedule assessment methods are used to represent uncertainties more realistically and to identify critical developments at an early stage. The FAIR experience also highlights the importance of clear project management structures. Methods and tools alone are not sufficient in highly complex research infrastructure projects. What is essential is the ability to identify the key main objectives and to maintain the necessary highest focus to achieve these objectives despite the technical, organizational and strategic interdependencies and complexity. This paper describes the integrated FAIR project management approach and the role of the PMO in coordinating multidisciplinary project activities within the FAIR and GSI campus environment.

The production of the new superconducting magnets for the luminosity upgrade of the LHC is in full swing. The performance of the magnets is probed by means of detailed magnetic measurements of the transfer function and field quality of the various families of magnets, i.e. triplet quadrupoles and separation and recombination dipoles. In this paper, the current situation in terms of magnetic properties is presented and reviewed in detail. Furthermore, dedicated beam dynamics simulations to address the possible issues for the various families of magnets are presented.

For the cSTART project the Institute for Beam Physics and Technology (IBPT) at the Karlsruhe Institute of Technology (KIT) introduced with Snipe-IT a new system to manage all accelerator related components. As the new components arrive, one of the first step is entering them into the asset database, which creates a unique identifier. This identifier is then also used during the quality inspection process as the main reference. The asset-to-asset associations possible with Snipe-IT provide a simple and efficient method for structuring the components in cabinets and along the storage ring. The flexible custom fields allow to track references to other data sources, which provide the more technical information such as CAD drawings, cable routing and device documentation. In addition, it also allows to track component specific information. This contribution describes the established workflows, status and lessons learned using a generic IT asset management system for accelerator component management.

The accelerator complex for the Facility for Antiproton and Ion Research (FAIR) is currently being built in Darmstadt, Germany. After the arrival of the cold box for the central cryogenic facility (CRYO2) in winter 2023, the installation of the accelerator components in the machine and supply tunnels started early 2024. Meanwhile the installation has moved forward. CRYO2 has been handed over to the commissioning team and the commissioning is in progress. The accelerator installation is ongoing in all parts of the beamlines of the High Energy Beam Transfer Lines (HEBT), the Super Fragment Separator (SFRS) and the Heavy Ion Synchrotron (SIS100). In parallel, the installation plans for the experiments (NUSTAR and CBM) are being developed and installation preparations are taking place. In this paper the status and challenges of the machine installation in those areas are presented and an outlook for the next steps towards realisation of the project phases for Early and First Science is given.

ALBA is working on the upgrade project that shall transform the actual storage ring, in operation since 2012, into a 4th generation light source, in which the soft X-rays part of the spectrum shall be diffraction limited. The project was launched in 2021 with an R&D budget to build prototypes of the more critical components. The storage ring upgrade is based on a MBA lattice which has to comply with several constraints imposed by the decision of maintaining the same circumference (269m), the same number of cells (16), the same beam energy (3GeV), and as many of the source points as possible unperturbed. At present, the lattice optimization, iterating with the technical constraints of space and performance, is ongoing. This paper presents the situation of the project, with the present proposed lattice and equipment design; the status of the prototyping of magnets, pulsed elements. vacuum chambers, buttons BPMs, and girders; the proposed RF system with fundamental and harmonics cavities; and the general context of the upgrade.

A new injector called NEWGAIN will be added to the SPIRAL2 Linear Accelerator in parallel with the existing one. It will be mainly composed of an ion source and a Radio Frequency Quadrupole (RFQ) connected to the superconductive LINAC. The RFQ is a standard four-vane bulk copper cavity, composed of 7 segments of about 1m. The new RFQ will accelerate at 88.05MHz particles with charge-over-mass ratio (Q/A) between 1/3 and 1/7, from 10 keV/u up to 590 keV/u. This paper will present the status of the RFQ section fabrication and its necessary support systems. The fabrication and delivery of these components will lead to its installation, which is a major milestone for the project.

INFN LASA is advancing its in-kind contribution to the PIP-II project at Fermilab, with significant progress achieved in both cavity production and testing infrastructures. The main activity is the fabrication of 38 five-cell β = 0.61 superconducting cavities for the LB650 section of the linac. Manufacturing is well advanced with mechanical production of the series cavities progressing while the two pre-series ones are being used to validate the complete industrial workflow, including surface processing and final preparation, that is mostly entrusted to industrial partners. Crucial to ensure compliance with the stringent performance requirements of PIP-II, all cavities will undergo final qualification through a vertical cold tests facility at DESY AMTF (Germany) that is being finalized and commissioned. Lastly cavities will proceed with the delivery to CEA Saclay (France) as fully validated components ready for string assembly. This contribution summarizes the status of these activities, presenting updates from the manufacturing of series cavities, results from pre-series qualification and recent upgrades to both LASA and DESY the testing infrastructures.

The SPIRAL2 facility at GANIL (Caen, France) has been operational since 2019. In 2027, the DESIR facility will begin receiving beams from the SPIRAL1 facility. At a later stage, DESIR will also receive radioactive ion beams from the S3-LEB facility, connected to the S3 separator of SPIRAL2. Construction of the DESIR building was completed in 2025. Many components of the beamline systems have already been manufactured and stored on-site at GANIL. Additionally, several experimental setups are currently under development and in the process of full qualification at partner laboratories, including HRS, GPIB, and PIPERADE at LP2IB, MLLTRAP and LINO at the ALTO-LEB facility (IJCLab, Orsay), and MORA at LPC-Caen. The DESIR facility requires long transfer and distribution beamlines to deliver beams to the experimental setups. Those beams can be passing throught many purification devices as high resolution separator and radio-frequency cooler buncher for high selection, emittance reduction and bunching. These lines are designed to transport mono-charged radioactive ion beams with energies up to 60 keV. Since 2012, various electrostatic systems have been developed and thoroughly reviewed as part of the beamline design process. This paper focuses on the already advanced installation of a beamline section and associated utilities and auxiliary systems located in the original GANIL building, which will enable the transfer of beams from the SPIRAL1 facility. It also provides a brief overview of the beam optics for the lines to be installed in the experimental hall, which will serve the experimental setups dedicated to nuclear physics research.
