Properties of a PIN photodiode as a neutron detector

The properties as a neutron detector of a silicon photodiode of type Hamamatsu S3590-02 in conjunction with a multi-channel analyser Alphatron-3C were investigated in an Am-Be calibration field at the department of nuclear engineering at the University of Madrid. Since the photodiode is sensitive to charged particles, we covered it with two types of converters to enable its response to thermal ...

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...

A neutron detector using integrated circuits

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...

Design and calibration of a passive detector for separating neutron, proton and alpha particles in mixed radiation fields

In this study, calibration process was carried out for deigned new CR-39 nuclear track detector for protons, neutrons and alpha particles separately under the same etching condition. In order to aim this purpose, americium-beryllium standard source (241Am-Be) and Plexiglas phantom for neutron irradiation, brass collimators and americium standard source (241Am) for alpha irradiation and the acce...
