Point detector allow user to measure x-ray beam flux, each measures a different range of flux.Ion Chambers measure the highest flux. Our calibrated PIN Diodes can measure fluxes from 104 to 1010 photons/sec. Photomultipler Tubes (PMTs) with NaI and YAP crystals can measure fluxes from 0 to 105 photons/sec. Finally, the avlanche photodiode (APD) is our fastest single photon counting detector.

The APS Detector Pool has a silicon APD with active area of 10 x 10 mm2 and thickness of ~ 180 microns (Part # C30703FH from Excelitas). The APD is packaged with a multi-stage preamplifiers by ATIM in France (Contacts: Thanh Deschaux and Francis Raimbert). The APD comes with low and high voltage power supplies. The Detector Pool database model name is: "EXCELITAS_APD_10x10mm2".
