Abstract The Large-Sized Telescopes (LSTs) of the Cherenkov Telescope Array (CTA) are designed for gamma-ray studies focusing on low energy threshold, high flux sensitivity and rapid telescope repositioning. LST has a tessellated parabolic mirror 23 m diameter weight about 100 tons, with capability pointing to any position in sky 20 seconds or less catch transients. A 2 ton 3x3 camera, placed f...
Abstract – in this study, designing and manufacturing of solar imaging and tracking system in order to research and spectroscopy applications are investigated. The device has the ability to be used as a Telescope, spectroscope, spectrophotometer and spectrohelioscope. The results obtained from this device are used in the various field of research such as absorption spectra of the surface of the...

We have observed Markarian 421 during an extraordinarily high state in January and March 2001 with the CANGAROO-II imaging Cherenkov telescope. From 14 hours observations at a large zenith angle of ∼70◦, a signal of 298± 52 gamma-ray–like events was detected at E > 10 TeV with 5.7 σ significance. Under the assumption of power-law spectrum, we derived a steep energy spectrum of photon index ∼4.0...
