Paper Abstract

The Max Planck Advanced Study Group (ASG) at the Center for Free Electron Laser Science (CFEL) has designed the CFEL-ASG MultiPurpose (CAMP) instrument, which provides a unique combination of particle and photon detectors for experiments at 4th generation light sources. In particular, CAMP includes two sets of newly developed 1024 × 1024 pixel pnCCD imaging detector systems. The CAMP instrument has now been successfully employed during the first three beam times at LCLS, and we report here on practical experience gained for the operation of imaging pnCCD detectors at FEL facilities. We address a wide range of topics: pnCCD gain and energy calibration during experiments; suppression of optical light contamination in pumpprobe experiments; contamination of the pnCCD entrance window with sample material; effects of accidental direct impact on the pnCCDs of particles generated by the FEL beam impinging on the experimental setup; and the effect of accidental direct exposure of a pnCCD to the focused and unattenuated X-ray beam. These lessons learned will help us to further improve operation of pnCCDs in future FEL experiments.
