Simulation of a Neutron Detector for Real Time Imaging Applications

Monte Carlo Method is used to simulate a double layer gadolinium-amorphous silicon thermal neutron detector. The detector fabricated in pixel array configuration has various applications including neutron imaging. According to the simulation results, a detector consisting of a gadolinium (Gd) film with thickness of 2-4 ~m, sandwiched properly with two layers of sufficiently thick (-30 ?µm) hydr...

Development of a Position Sensitive Neutron Detector with High Efficiency and Energy Resolution for Use at High-Flux Beam Sources

We are developing a high-efficiency neutron detector with 1 cm position resolution and coarse energy resolution for use at high-flux neutron source facilities currently proposed or under construction. The detector concept integrates a segmented (3)He ionization chamber with the position sensitive, charged particle collection methods of a MicroMegas detector. Neutron absorption on the helium pro...

Amorphous Silicon Based Neutron Detector

Perforated Semiconductor Neutron Detector Modules

Compact neutron detectors are being designed and tested for use as low-power real-time personnel dosimeters. The neutron detectors are pin diodes that are mass produced from high-purity Si wafers. Each detector has thousands of circular perforations etched vertically into the device. The perforations are backfilled with 6 LiF to make the pin diodes sensitive to thermal neutrons. The prototype d...

Modification of a Uv Spectrometer into a Neutron Detector Using Neutron-sensitive Scintillating Material

This report describes the design and development of a plastic scintillating high energy neutron detector to be implemented as a micro-class satellite payload. The primary function of this detector is to identify and characterize the energy distribution of solar accelerated neutrons resulting from massive solar events. Accelerated neutrons will be identified by a pulse counting system using the ...
