Description

Imaging Atmospheric Cherenkov Telescopes (IACTs) play a crucial role in probing the high-energy universe through the detection of very-high-energy gamma rays. The accuracy and reliability of these instruments are contingent upon precise calibration methodologies. Examining the ring-shaped images generated by muons within IACTs offers a robust and accurate approach for calibrating the telescopes' optical throughput and tracking changes in their optical point-spread function. Muons are particles generated from cosmic-ray interactions with Earth's atmosphere. Their well-characterized properties, including their known flux and energy spectra, make them invaluable for calibration purposes.
The talk aims to relieve the significance of muon calibration techniques as indispensable tools in advancing the precision and reliability of IACT observations. Additionally, we will discuss the physics of extensive air showers, recent discoveries in the field of gamma-ray astronomy, and encountered problems. It seeks to stimulate further research and collaborative efforts toward gamma-ray astronomy and optimizing calibration methodologies for the next generation of IACT.
