Readout calibration of Cherenkov telescope data acquired by Domino Ring Sampler v.4 chips - a status report after one year of research — •Mario Hörbe — Ruhr-Universität Bochum, Germany

Very-high-energy gamma-ray astronomy aims to give insights into the most energetic phenomena in our Universe. Earthbound Cherenkov telescopes measure Cherenkov light emitted by constituents in atmospheric showers which are initiated by primary high-energy particles. Current Cherenkov telescope cameras, e.g. operated in the MAGIC and FACT experiments, utilize the fourth generation of Domino Ring Sampler (DRS4) chips to acquire data at a high pace. The future Cherenkov Telescope Array (CTA) will implement this technology and acquire vast amounts of DSR4-based data, requiring precise calibration. We aim at developing readout data calibration techniques between the requirements of calibration precision and computational resource consumption, to be operated in CTA. The status as well as the challenges and objectives of the project will be presented.
