Readout electronics testing during mass production of FlashCam cameras for the Cherenkov Telescope Array

摘要

The Cherenkov Telescope Array (CTA) will be the future observatory for ground-based TeV gamma-ray astronomy. At two sites, one in the northern and one in the southern hemisphere, CTA will feature about one hundred telescopes of different size classes in order to significantly improve the sensitivity and energy range with respect to current Cherenkov facilities. FlashCam is a camera system proposed for the medium-sized telescopes of CTA that implements a fully-digital readout and trigger processing, which allows the reconfiguration of the trigger algorithm and the signal shaping. For the mass production of a substantial number of FlashCam cameras, efficient and reliable testing routines have been developed. In this contribution, the concept and the procedures for large-scale testing of the readout electronics are outlined. Additionally, a fast multi-channel pulse generator specifically designed for the functional testing of FlashCam FADC modules setup is presented.
