Conveners
Detectors for FELS, Synchrotron and other advanced Light sources

Low Gain Avalanche Diodes (LGADs) represent the state-of-the-art in timing measurements, and will instrument the future Timing Detectors of ATLAS and CMS for the High-Luminosity LHC. While initially conceived as a sensor for charged particles, the intrinsic gain of LGADs makes it possible to detect low energy X-rays with good energy resolution and excellent timing (tens of picoseconds). Using...
Starting this autumn, the Swiss Light Source is undergoing an upgrade to a diffraction limited light source and with this the coherent flux will increase with up to two orders of magnitude. This poses a huge challenge for single photon counting detectors which despite being incredibly successful still suffers from pulse pile-up at high rates. In this talk we present our strategy for single...
Xray Free Electron Lasers (XFELs) produce extremely high intensity pulses of photons with ultrashort duration. Planned upgrades to these facilities will increase photon energies above 20keV as well as increasing pulse repetition rates to greater than 1MHz. At these energies silicon has poor quantum efficiency and is susceptible to radiation damage, so new detector materials must be used....
The advent of diffraction limited storage ring synchrotron facilities is pushing the requirements of X-ray detectors into a new regime. The Diamond II synchrotron will deliver X-ray fluxes ~10$^{12}$ ph/mm$^2$/s at the detector for some experiments. At such high fluxes the photons arrive at such a rate that conventional photon counting detectors are unable to make accurate measurements....
