Detector Seminar Prof. dr. R. Klanner

Wednesday the 9th of October there has been a seminar by  prof. dr. Klanner regarding the European X-Ray Free-Electron Laser XFE.

In short, the high instantaneous intensity and the high repetition rate of 4.5 MHz of the European X-Ray Free-Electron Laser XFEL pose new challenges for imaging detectors. The specific requirements for the detectors are a dynamic range of up to more than 104 photons of typically 12.4 keV per pixel for an XFEL pulse duration of < 100 fs, with a clear separation of 1 from 0 photons, and a radiation tolerance for doses up to 1 GGy for 3 years of operation. Within the AGIPD Collaboration the Hamburg group has systematically studied the consequences of these requirements for p+n silicon sensors and has optimized the sensor design using TCAD simulations. In February 2013 the first batches have been received and first measurements show that the optimization has been successful.
