Performance of the SST-1M telescope of the Cherenkov Telescope Array observatory

Abstract

The single mirror small-size telescope (SST-1M) is one of the telescope projects being proposed for the Cherenkov Telescope Array observatory by a sub-consortium of Polish and Swiss institutions. The SST-1M prototype structure is currently being constructed at the Institute of Nuclear Physics in Cracow, Poland, while the camera will be assembled at the University of Geneva, Switzerland. This prototype enables measurements of parameters having a decisive influence on the telescope performance. We present results of numerical simulations of the SST-1M performance based on such measurements. The telescope effective area, the expected trigger rates and the optical point spread function are calculated.

The small size telescope projects for the Cherenkov Telescope Array

“…Simulations indicate that the SST-1M design satisfies the required performance for SSTs [3]. The camera calibration strategies and calibrations with muons are described in [8,9].…”

Development of an optical system for the SST-1M telescope of the Cherenkov Telescope Array observatory

“…The analysis confirmed that the optical system meets the requirementsover 80% of energy was enclosed within <0.25°. The details related to the current SST-1M optical simulation can be found in [7].…”

Calibration strategies for the Cherenkov Telescope Array

“…In both cases, 24 m "large-size" telescopes 6 will be located in the center, surrounded by 12 m "medium-size" 7,8 and 4 m "small-size" telescopes. [9][10][11] Currently prototyped technologies employ traditional single-mirror designs, either with parabolic 6 or Davies-Cotton reflector, 7 and innovative dual-mirror designs. 8,11,12 The cameras will be equipped either with photomultipliers (PMTs) [13][14][15] or Silicon photomultipliers (SiPM).…”
