ON-THE-FLY SCANNING: IMPROVING SCAN TIME OF XAFS AT BM08-XAFS/XRF BEAMLINE
3229
In this work, we present the use of PandABox timing module to implement position-based and time-based on- the-fly scanning to continuously acquire data at the X-ray Absorption Fine Structure (XAFS) and X-ray Fluorescence (XRF) beamline of SESAME synchrotron light source. For position-based scanning, we first developed a module that automatically partitions the user-defined energy and Bragg angle ranges into sub-intervals. Within each sub-interval, the energy-angle mapping is linearly approximated to main- tain accuracy within acceptable margins. The method then integrates the position encoding of the Double Crystal Monochromator (DCM) Bragg angle with the synchronous triggering of multiple detectors, including ionization cham- bers (ICs) and a KETEK SSD detector. For time-based scanning, PandABox is pre-configured to generate triggers at fixed time exposure time intervals. Improvements, per- formance and comparative results are also discussed in this work.
