The Energy Resolution of The MAGIC Telescope

In the field of gamma-rays Astrophysics in the – energy domain, the understanding of spectra of detected gamma rays is necessary in developing models for acceleration, emission, absorption and propagation of very high energy particles in their sources and in space. Therefore, high precision in the measurement of the energy of observed gammas is important. On the example of the 17 ø MAGIC telescope, we study in this paper the energy resolution of an imaging Cherenkov telescope operating in stand-alone mode in the – energy range.
