Time and charge calibration of Cherenkov telescope data acquired by Domino Ring Sampler 4 chips — •Mario Hörbe¹, Marlene Doert¹, Kai Brügge², Jens Buss², Christian Bockermann², and Alexej Egorov² — ¹Ruhr-Universität Bochum — ²TU Dortmund

Very-high-energy gamma-ray astronomy aims to give an insight into the most energetic phenomena in our Universe. Earthbound Cherenkov telescopes can measure Cherenkov light emitted by atmospheric particle showers which are produced by incoming cosmic particles at high energies. Current Cherenkov telescopes, e.g. operated in the FACT and the MAGIC experiments, utilize Domino Ring Sampler 4 (DRS4) chips for recording signals at high speed coming from the telescopes’ cameras. DRS4 chips will also be used in the cameras of the Large-Size telescopes of the projected Cherenkov Telescope Array (CTA). We aim at developing a software solution for the calibration of DRS4 data based on the streams-framework, a software tool for streaming analysis which has been developed within the Collaborative Research Center SFB 876. The objectives and the current status of the project will be presented.
