Electron Multiplying Charge Coupled Devices, EMCCD are used as x-ray detectors. The NSLS-II Soft Inelastic Scattering (SIX) beam line has two EMCCDs for detection in the spectrometer arm. with high resolving power disperses x-rays vertically. vertical position on sensor plane is related to its energy. This allows very accurate energy measurements through coordinates. X-rays interact silicon and...
