Simulated Neutron Response Functions of Phoswich-Type Neutron Detector and Thin Organic Liquid Scintillator

Neutron response functions of a phoswich neutron detector and thin organic liquid scintillator were simulated using the multi-purpose Monte Carlo code MCNPX, incorporating functions of light outputs, energy resolutions, and uniformity of scintillation. The simulated response functions were verified by response-function measurement for high-energy neutrons produced by bombarding thin lithium tar...

A novel, SiPM-array-based, monolithic scintillator detector for PET.

Silicon photomultipliers (SiPMs) are of great interest to positron emission tomography (PET), as they enable new detector geometries, for e.g., depth-of-interaction (DOI) determination, are MR compatible, and offer faster response and higher gain than other solid-state photosensors such as avalanche photodiodes. Here we present a novel detector design with DOI correction, in which a position-se...

A large area plastic scintillator detector array for fast neutron measurements

A large area plastic scintillator detector array(∼ 1×1 m) has been set up for fast neutron spectroscopy at the BARC-TIFR Pelletron laboratory, Mumbai. The energy, time and position response has been measured for electrons using radioactive sources and for mono-energetic neutrons using the 7Li(p,n1) Be*(0.429 MeV) reaction at proton energies between 6.3 and 19 MeV. A Monte Carlo simulation of th...
