XRF maps using continuous scanning of the x-stage removes the deadtime associated with step scans allowing for larger and faster XRF maps. A 200 x 200 point map may now be done in about 2 hrs if the sample is concentrated enough.
Allows somewhat larger samples/areas to be scanned especially concentrated samples with a dwell time per point as low as 0.01 s.
Two available - Xspress 3 electronics, 1000 kHz count rate per element in XAFS mode, up to 1.5 MHz in XRF at 90 degree to X-ray beam (Both Si detectors can be used simultaneously).
16 MEDIPIX3 chips read-out at 100 frames per second in continuous mode or 1000 frames per second in burst mode. A total detection area of the 3-module EXCALIBUR detector is 115 mm × 100 mm with a small 6.8 mm wide inactive region between modules at a very high spatial resolution small pixel size of 55 microns.
FMB Oxford APD detector is an ultra-fast detector, using an avalanche photo diode up to 20keV.
Ultrafast detector ideal for experiments with a large dynamic range, time resolved measurements and fast photon counting.
