Abstract

An integrating fast readout detector is being developed for the X-ray Pump Probe (XPP) instrument at the Linac Coherent Light Source (LCLS). The detector is based on X-ray Active Matrix Pixel Sensors (XAMPS) with their dedicated readout ASICs. It covers a dynamic range of more than 10,000 photons of 8 keV energy with a resolution better than half photon FWHM. The frame of 1024 Ã— 1024 pixels will be read out within the repetition rate of the X-ray laser pulses which will be as fast as 120 Hz. The structure of the sensor allows full fill factor and -100% efficiency at the energy of interest.
