A detailed numerical procedure has been developed to simulate the mechanical configurations and optical properties of Imaging Atmospheric Cerenkov Telescope systems. To test these procedures a few existing ACT arrays are simulated. First results from these simulations are presented.
The JUNO neutrino detector system is simulated using Monte-Carlo and analytical methods. A large number of proton decay events are also simulated. Preliminary results from this endeavor are presented in the present article.
The Hyper-Kamiokande Water-Cherenkov Neutrino Detectors are simulated using Monte-Carlo and analytical methods. A few simple events are also simulated and these preliminary results are presented.
The modulation of high-energy transients' (or steadily emitting sources') light curves due to the imperfect alignment of the detector's view axis with the spin axis in a spin-stabilized satellite is derived. It is shown how the orientation of the detector's view axis with respect to the satellite's spin axis may be estimated using observed light curves. The effects of statistical fluctuations are considered. Conversely, it is shown how the attitude of a spin-axis stabilized satellite as well as the unknown position of a celestial source of high-energy photons may be determined using a detector whose view-axis is intentionally kept inclined and is known accurately beforehand. The case of three-axes stabilized satellites is also discussed.
A detailed Monte-Carlo code has been developed from basic principles that simulates almost all of the basic photon and charged particle interactions. The code is used to derive the response functions of a high energy photon detector to incident beams of photons of various energies. The detector response matrices (DRMs) are calculated using this code. Deconvolution of an artificially generated spectrum is presented.
