  • Cosmic-ray mass composition investigations through atmospheric Cerenkov technique - a simulation study 
    Bhat, C. K; Kaul, R. K; Sapru, M. L; Bhat, C. L (Astronomical Society of India, 2001)
    The 4-element TACTIC Cerenkov telescope array at Mt. Abu comprises a central Imaging Element equipped with a 349- pixel Cerenkov imaging camera and three Vertex Elements, each of which is equipped with a special duplex ...
  • 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
  • Energy resolution of the TACTIC imaging element 
    Sathyabama, N; Dhar, V. K; Koul, M. K; Bhat, C. L (Astronomical Society of India, 2001)
    We explore here the possibility of using artificial neural network (ANN) for characterization of atmospheric Cerenkov events (progenitor type and energy) detected by the imaging gamma-ray telescope array, TACTIC.
  • Multinode data acquisition and control system for the Vertex Elements of the TACTIC telescope array 
    Yadav, K. K; Bhatt, N; Kaul, S. R; Koul, R (Astronomical Society of India, 2001)
    An interrupt based multinode data acquisition and control system has been developed for the three Vertex Elements of the TACTIC telescope array. The paper describes the salient design features of the hardware and software ...
  • Novel image and non-image parameters for efficient characterisation of atmospheric Cerenkov images 
    Razdan, A; Haungs, A; Rebel, H; Bhat, C. L (Astronomical Society of India, 2002)
    We make a comparative study of the classification potential of various image and non-image parameters which are measurable with the TACTIC array focal plane instrumentation. The image parameters include conventional Hillas ...
  • Threshold energy estimates of TACTIC array elements 
    Sapru, M. L; Satyabhama, N; Koul, M. K; Tickoo, A. K; Bhat, C. L (Astronomical Society of India, 2002)
    Using the CORSIKA-code based simulation studies, we present here results on the gamma-ray and the cosmic-ray proton trigger-thresholds for the Imaging-Element and the 3 Vertex-Elements of the TACTIC atmospheric Cerenkov ...
