Abstract
The Cherenkov Telescope Array (CTA) will explore with unprecedented precision the Universe in the gamma ray domain covering an energy range from 50 GeV to more the 300 TeV. To cover such a broad range with a sensitivity which will be ten time better than actual instruments, different types of telescopes are needed: the Large Size Telescopes (LSTs), with a 24 m diameter mirror, a Medium Size Telescopes (MSTs), with a 12 m mirror and the small size telescopes (SSTs), with a 4 m diameter mirror. The single mirror small size telescope (SST-1M), one of the proposed solutions to become part of the small-size telescopes of CTA, will be equipped with an innovative camera. The SST-1M has a Davies-Cotton optical design with a mirror dish of 4 m diameter and focal ratio 1.4 focussing the Cherenkov light produced in atmospheric showers onto a 90 cm wide hexagonal camera providing a FoV of 9 degrees. The camera is an innovative design based on silicon photonuiltipliers (SiPM) and adopting a fully digital trigger and readout architecture. The catitera features 1296 custom designed large arca hexagonal coupled to hollow optical concentrators to achieve a pixel size of almost 2.4 ern. The Si PM is a custom design developed With I Ituiu ian iatau and with its active area of almost 1 ern is one Or the largest tiioiiolit hitSi PI\I existing. Also the. optical concentratot"s are innovative being light funnels leis made of a polycarboliate substrate coated with a costom designed UV-enhancing coating. The analog signals Conning from tlIC Si PM are fed into the fully digital readout electronics, where digital data are processed by high-speed UPGAs both lOr trigger and readout. The trigger logic, implemented into an Virtex 7 FPGA, uses the digital data to elaborate a trigger decision by matching data against predefined patterns. This approach is extremely flexible and allows improvements and continued evolutions of the system. The prototype camera is being tested in laboratory pro tr to its installation expected in fall 2017 on the telescope prototype in Krakow (Poland). In this contribution, we will describe the design of the camera and show the performance measured in lalii-Jratory.
