Abstract

A variant of testing threshold SiO2 aerogel Cherenkov detectors using cosmic radiation is described. The implementation requires a minimum amount of additional electronics and does not involve massive absorber layers (e. g., lead). The method makes it possible to accurately determine efficiency of detectors under study and to study operation of detectors in different energy ranges for relativistic charged particles. Good agreement between the results of the simulation and measurements was obtained.
