Mechanical design and deflection analysis of TACTIC gamma-ray telescope

Abstract

The high sensitivity gamma-ray telescope TACTIC to be set up at Gurushikar is presently being manufactured at the Central Workshop, Bhabha Atomic Research Centre (BARC). Deflection analysis of the mirror basket assembly, which holds 34 spherical mirror facets weighing about 1 tonne, has been performed to arrive at the deflection in the position of the focal point of the mirror combination at various zenithal positions. The results of this analysis and the mechanical design aspects of the telescope are discussed
