Issue Date: | 2019 | Journal: | POS PROCEEDINGS OF SCIENCE | Volume: | 36th International Cosmic Ray Conference (ICRC2019) | Number: | 358 | 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. | Conference Name: | 36th International Cosmic Ray Conference (ICRC2019) | Conference Place: | Madison, WI, U.S.A | Conference Date: | July 24th-August 1st, 2019 | URI: | http://hdl.handle.net/20.500.12386/28837 | URL: | https://pos.sissa.it/cgi-bin/reader/conf.cgi?confid=358, https://pos.sissa.it/358/744/ |
