Zusammenfassung:
In October 2019, the central 28 m telescope of the H.E.S.S. experiment has
been upgraded with a new camera. The camera is based on the FlashCam design
which has been developed in view of a possible future implementation in the
Medium-Sized Telescopes of the Cherenkov Telescope Array (CTA), with emphasis
on cost and performance optimization and on reliability. The fully digital
design of the trigger and readout system makes it possible to operate the
camera at high event rates and to precisely adjust and understand the trigger
system. The novel design of the front-end electronics achieves a dynamic range
of over 3,000 photoelectrons with only one electronics readout circuit per
pixel. Here we report on the performance parameters of the camera obtained
during the first year of operation in the field, including operational
stability and optimization of calibration algorithms.
