Improved performances of the NectarCAM, a Medium-Sized Telescope Camera for the Cherenkov Telescope Array

Abstract

NectarCAM is a camera developed to detect Cherenkov light between 80 GeV and 30 TeV. It will equip the medium-sized telescopes (MST) of the Cherenkov Telescope Array Observatory (CTAO). The camera comprises 265 modules, covering a field of view of 8 degrees. Each module consists of 7 photomultiplier Tubes (PMTs) equipped with light guides and a front-end board performing the data capture. NectarCAM is based on the NECTAr chip, which combines a switch capacitor array sampling at 1GHz and a 12-bit Analog to Digital Converter (ADC). The NectarCAM camera is currently under integration in CEA Paris-Saclay (France). In this contribution, I focus on the ongoing performance tests for its characterization and calibration before deployment on the CTAO North site.
