Description
For Free Electron Lasers the number of scattered photons per bunch is enough to record a full image. At the same time single photon sensitivity is required. An additional challenge at the European FEL stems from its time structures with 10 bunch trains per second each containing 2700 bunches (at 4.5 MHz). To meet these challenges the AGIPD-system has been under development. Full modules have now been produced and tested at Synchrotron Storage rings.
An important part of the science performed at Free-Electron Lasers will be in the soft X-ray range, between 250 eV and 3 keV. PERCIVAL is a dedicated project to develop a CMOS based imager with up to 13 Mpixels, with 120 Hz frame-rate and having single photon sensitivity down to 250 eV. First back-thinned prototypes have been produced and extensively tested at various synchrotrons. Also these results will be discussed.
Finally, future directions will be briefly presented.
