Characterization of X-Ray Diamond Detector by Monte Carlo Method

Abstract

The use of diamond as material for X-ray detector is subject of investigation and practice in radiotherapy, space and material science and technology. This paper presents the results of application of Monte Carlo method for simulation of photon transport through diamond detector. The aim is restitution and demonstrating of numerical technique for characterization of electrical properties for different detector conditions and configurations. Monte Carlo code was adopted to determine the energy deposited and dose distribution in the structure of diamond detector. Our results show that the use of numerical simulations may be of essential help in design of diamond detector systems.

Atomic spectrometry update–X-ray fluorescence spectrometry

“…In studying the spectroscopic response at room temperature for three radioisotope sources ( 57 Co, 133 Ba and 241 Am) the authors obtained distorted spectra and opted to use Monte Carlo (MC) simulation in order to establish the true detector response function. It was also concluded by Stankovic et al 54 that numerical simulation tools such as MC were likely to be essential for the understanding and design of diamond-based X-ray detectors. A detailed study by Kostamo and co-workers 55 of the structural and electrical characteristics of TlBr crystals for X-ray detectors identified smallangle grain boundaries in the material, which were shown to be correlated with detector performance.…”

“…FOTELP-2K10 code has great competency in successful resolving of radiation transport problems which review interactions gamma and X-rays with electronic components and devices, such as MOSFET dosimeters [12,13], CdZnTe detector [14] and diamond detector [15].…”

Monte Carlo Analysis of the Influence of Different Packaging on MOSFET Energy Response to X-rays and Gamma Radiation

“…Numerical method Characterization of radiation sensing MOSFET by Monte Carlo method was made with FOTELP-2K10 code for incident photons with dierent energies. FOTELP--2K10 code has great competency in successful resolving of radiation transport problems which review interactions of gamma and X-rays with electronic components and devices, such as MOSFET dosimeters [9,11], CdZnTe detector [12], diamond detector [13] and silicon carbide detector [14]. Physical rigor is maximized by employing the best available cross-sections and high speed routines for random values sampling from their distributions, and the most complete physical model for describing the transport and production of the photon/electron/positron cascade from 100.0 MeV down to 1.0 keV.…”
