Possible Discrimination between Gamma Rays and Hadrons using Čerenkov Photon Timing Measurements
Atmospheric Čerenkov Technique is an established methodology to study TeV energy gamma rays. However the challenging problem has always been the poor signal to noise ratio due to the presence of abundant cosmic rays. Several ingenious techniques have been employed to alleviate this problem, most of which are centred around the Čerenkov image characteristics. However there are not many technique...
متن کامل2 Absorption of Gamma - Rays by Photon Photon Pair
We determine the physical parameters (magnetic field and Doppler factor) of the homogeneous synchrotron self-Compton model allowed by the observed X–ray to gamma-ray spectra and variability of Markarian 501 during the 15–16 April 1997 flaring activity. We find that magnetic fields between 0.07 G and 0.6 G and Doppler factors between 12 and 36 could fit (depending on observed variability time sc...
متن کاملThe Role of Fluctuations in Atmospheric Čerenkov Technique
In the absence of a standard source of gamma rays or hadrons of known energy one has to study the details of production of Čerenkov light at the observation level only through detailed simulation studies. Recently such studies have become all the more important in view of the various techniques resulting from such studies, to distinguish between gamma ray initiated events from those generated b...
متن کاملDigital discrimination of neutrons and gamma-rays in liquid scintillators using wavelets
A novel algorithm for the digital discrimination of neutrons and gamma-rays in a mixed radiation field is presented. Most of the pulse shape discrimination methods in scintillation detection systems use time-domain features of the signal (e.g. charge comparison method or constant-time discrimination). However, there are no frequency-domain discrimination methods up to date in the literature. Ou...
متن کاملMeasurements of Photonuclear Reactions Induced with Linearly Polarized Gamma Rays
This thesis reports the first measurements of cross sections and asymmetries for gamma ray induced emission of neutrons from Se. These measurements are part of a broader project to obtain transition widths relevant to determining the weak-magnetism corrections to the standard Fermi function for the energy spectrum of electrons emitted in beta decay of radioactive nuclei. The measurements were p...
