Phoswich detectors were developed to detect low-intensity, low-energy gamma rays, X-rays, as well as alpha and beta particles efficiently in a higher-energy ambient background. Some detector designs can measure and separately identify all energies simultaneously. A phoswich ("phosphor sandwich") is a combination of scintillators with dissimilar pulse shape characteristics optically coupled to each other and to a common PMT (or PMTs). Pulse shape an… WebMay 24, 2007 · A phoswich detector was developed to measure neutron energy spectra from a few MeV to a few hundreds MeV in aircrafts and space crafts. Radiation fields, which both crafts are exposured, consist of neutrons, gamma rays, protons, etc. The phoswich detector can measure neutrons separately from gamma rays and protons.

WebThe phoswich detector used in this work consists of two scintillation crystals (Fig. 1): a CsI(Tl) crystal to perform gamma-rays spectroscopy and a BGO crystal, surrounding the CsI(Tl) , to identify and reject scattered photons in the CsI(Tl) . The roles of CsI(Tl) and BGO crystals in this phoswich detector are similar to the roles of primary and WebIt is found that the 1.46-MeV gamma-ray–led background can be reduced by 40% by the phoswich detector operating in anticoincidence mode whereas the 1.31-MeV beta-particle–led background is almost unaffected.
