22 Jul 2019 | | Abstract: | Astri-Horn is a Small-Sized Telescope (SST) for very-high energy gamma-ray
astronomy installed in Italy at the INAF "M.C. Fracastoro" observing station
(Mt. Etna, Sicily). The ASTRI-Horn telescope is characterized by a dual-mirror
optical system and a curved focal surface covered by SiPM sensors managed by a
innovative fast front-end electronics. Dedicated studies were performed to
verify the feasibility of the calibration through muons on the relatively small
size of the primary mirror (~4 m diameter), as in the case of larger Cherenkov
telescopes. A number of tests were performed using simulations of the
atmospheric showers with the CORSIKA package and of the telescope response with
a dedicated simulator. In this contribution we present a preliminary analysis
of muon events detected by ASTRI-Horn during the regular scientific data taking
performed in December 2018 and March 2019. These muon events validate the
results obtained with the simulations and definitively confirm the feasibility
of calibrating the ASTRI-Horn SST telescope with muons. | | Source: | arXiv, 1907.9197 | | Services: | Forum | Review | PDF | Favorites | |
