Comparing the time-of-fight techniques in a high-energy gamma-ray telescope

摘要

The use of the time-coordinate compensation technique in detectors of the time-of-flight (TOF) system of a typical high-energy gamma-ray telescope is considered. Detection of gamma rays with energies of 10 and 1000 GeV by the TOF system of the telescope is simulated. Two variants of the TOF system design with and without the use of the time-coordinate compensation technique are compared. One of the techniques is used in each variant in both detectors of the TOF system. For both variants, the TOF spectra of secondary particles produced in the telescope converter are calculated. It is shown that the use of the coordinate compensation method is advantageous in the detection of gamma rays with an energy of 1000 GeV.
