[GA166] Development of a strategy for calibrating the novel SiPM camera of the SST-1M telescope proposed for the Cherenkov Telescope
CTA will comprise a sub-array of up to 70 small sized telescopes (SSTs) in the southern array. Silicon photomultipliers (SiPM) cameras of gamma-ray telescopes can achieve good performance even during high night sky background conditions. The SST-1M project, a 4 m-diameter Davies Cotton telescope with 9 degrees FoV and a 1296 pixels SiPM camera, is designed to meet the requirements of the next generation of ground based gamma-ray observatory CTA in the energy range above 3 TeV. Defining a fully automated calibration strategy of SiPM cameras is of great importance for large scale production validation and online calibration. Relying on the CTApipe framework, the software developed by the SST-1M sub-consortium is designed to collect and analyze calibration data. The calibration of the SST-1M camera is based on the Camera Test Setup (CTS), a LED board fixed in front of the camera. The CTS LEDs are operated in pulsed or continuous mode to emulate signal and night sky background. Continuous and pulsed light data analysis allow to extract single pixel calibration parameters during CTA operation in order to extract signal charge, time and background level. The trigger efficiency and charge resolution measurements will be compared to simulations.
