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...

Proton beam dosimetry by CR-39 track-etched detector

Background: High and intermediate energy protons are not able to form a track in a solid state nuclear track detector (SSNTD) directly. However, such tracks can be formed through secondary particles created during primary radiation nuclear reactions in a SSNTD. Materials and Methods: The protons with primary energies of 9.6 and 30 MeV available at the cyclotron accelerator with corresponding lo...

Implementation of Hough Transform as Track Detector

1 Sponsored by the Bulgarian Science Fund, Grant No.I-801/98. Abstract. Hough Transform is a convenient tool for features extraction from images. In this paper an implementation of Hough Transform is onsidered for automatic track initiation in the surveillance radar space. The need of track initiation arises when there are many moving objects in the sensor surveillance volume and when it is not...

Characterisation of a planar germanium detector using a gamma scanner

A 300kBq Na source is placed between the front surface of planar detector and the position sensitive detector (PSD) as shown in figure 1(a). This source emits pairs of 511 keV positron annihilation photons in opposite directions. The germanium detector is placed in the focal plane of the system at a distance of 15 cm from the source whereas the PSD is at 5 cm from it in order to cover the full ...

A parameterization of nuclear track profiles in CR-39 detector

In this work, the empirical parameterization describing the alpha particles’ track depth in CR-39 detectors is extended to describe longitudinal track profiles against etching time for protons and alpha particles. MATLAB based software is developed for this purpose. The software calculates and plots the depth, diameter, range, residual range, saturation time, and etch rate versus etching time. ...
