  • Detector instrumentation and drive system for TACTIC gamma-ray telescope 
    Koul, R; Bhat, C. L; Tickoo, A. K; Kaul, I. K; Kaul, S. K; Kaul, S. R; Sapru, M. L; Rannot, R. C (Astronomical Society of India, 1993)
    TACTIC, a high sensitivity gamma-ray telescope is being set up at Gurushikar, Mt. Abu, to undertake comprehensive temporal and spectral studies of cosmic gamma-ray sources in the TeV energy range. The salient features of ...
  • Development of a large-area, wide-angle Cerenkov radiation detector for the MYSTIQUE gamma-ray telescope 
    Dhar, V. K; Yadav, K. K; Bhattacharyya, S; Kaul, R. K; Bhat, C. L; Koul, R; Kaul, S. R; Kaul, S. K (Astronomical Society of India, 1999)
    An ultra-sensitive, multi-detector gamma-ray telescope array is being setup at Mt. Abu for cosmic gamma-ray studies in the tens of TeV energy region. Here, we present the essential design features of the Cerenkov radiation ...
  • Drive control system for the TACTIC γ-ray telescope 
    Tickoo, A. K; Koul, R; Kaul, S. K; Kaul, I. K; Bhat, C. L; Bhatt, N (Astronomical Society of India, 1999)
    We present here some salient features of the hardware and software aspects of the 2-axes drive system developed for the TACTIC γ-ray telescope array. A test-report of its performance is also presented
  • A DSO-based system for temporal-profile extraction of atmospheric Cerenkov events 
    Tickoo, A. K; Kaul, S. K; Kaul, I. K; Koul, R; Bhat, C. L (Astronomical Society of India, 2000)
    The TACTIC array of Cerenkov telescopes, being set up at Mt. Abu, proposes to record time-profiles of atmospheric Cerenkov pulses with a view to exploit apparent differences in the associated time-parameters for a possible ...
