The Agile Gamma-ray Detector
The gamma-ray detector AGILE, operating in the energy range from 30 MeV to 50 GeV, is composed by a tracking part, a light calorimeter and an anticoincidence system. Here we describe the detector and its capabilities to determine the arrival direction and energy of the detected photons. The AGILE design is derived from a refined study of the GILDA project (Barbiellini et al. 1995, Morselli et a...
متن کاملXENON100 Detector Upgrade: Gamma Backgrounds
Research and development of the XENON100 Detector Upgrade is motivated by the search for Weakly Interacting Massive Particles (WIMPs). The purpose of this upgrade is to lower the overall background significantly and to double the fiducial volume while increasing the fiducial to total volume ratio in order to increase the efficiency of the detector. Monte Carlo simulations using Geant4 were used...

متن کاملGamma ray polarimetry using a position sensitive germanium detector
Imaging gamma-ray detectors make sensitive polarimeters in the Compton energy regime by measuring the scatter direction of gamma-rays. The principle is to capitalize on the angular dependence of the Compton scattering cross section to polarized gamma rays and measure the distribution of scatter directions within the detector. This technique is effective in a double-sided germanium detector betw...
متن کاملCharacterisation of a planar germanium detector using a gamma scanner
A 300kBq Na source is placed between the front surface of planar detector and the position sensitive detector (PSD) as shown in figure 1(a). This source emits pairs of 511 keV positron annihilation photons in opposite directions. The germanium detector is placed in the focal plane of the system at a distance of 15 cm from the source whereas the PSD is at 5 cm from it in order to cover the full ...
