A simple neutron counter based on a scintillator strip, a wavelength shifter rod, and a photomultiplier was constructed in order to compare the properties of such a detector to a commercially available He counter. A calculation of the number of photons per absorbed neutron shows that with the bright Li Gd (11BO3)3 scintillator, light levels should be sufficient to perform pulse height discrimin...

Considerable progress has been achieved recently to enhance the thermal neutron detection efficiency of solid-state neutron detectors that incorporate neutron sensitive materials such as B and LiF in Si micro-structured p-n junction diode. Here, we describe the design, fabrication process optimization and characterization of an enriched boron filled honeycomb structured neutron detector with a ...

The objective of this study is to demonstrate the feasibility of constructing a compact neutron detector that is sensitive to thermal and epithermal neutrons and has high rejection efficiency relative to gamma-ray background. A two-channel high-pressure He scintillation detector is considered for the detection of neutrons in coincidence mode. The detector consists of two large avalanche photodi...

High-fidelity, time-resolved measurements of the neutron flux from the implosion of DTandlor DD-filled capsules have been a challenging problem for the international inertial-confinement-fusion (ICF) community. A measure of the neutron production rate can provide valuable information on the quaIity of the implosion, such as the confinement time of the plasma. A time-resolving neutron detector i...

With the advancements and miniaturization in semiconductor technology, the circuits within integrated circuits have become increasingly sensitive to the effects of radiation, and therefore, are susceptible to improper functioning in high radiation fields. The researchers at Texas A&M University have been able to manipulate this disadvantage into an advantage for radiation detection applications...

A Prompt Gamma Ray Neutron Activation Analysis (PGNAA) system, incorporating an isotopic neutron source has been simulated using the MCNPX Monte Carlo code. In order to improve the signal to noise ratio different collimators and a filter were placed between the neutron source and the object. The effect of the positioning of the neutron beam and the detector relative to the object has been studi...
