Characteristics of TlBr single crystals grown using the vertical Bridgman-Stockbarger method for semiconductor-based radiation detector applications

1 Introduction Semiconductor radiation detectors are of considerable technological importance due to their increasing use in medical imaging, and industrial and transportation security applications [1 , 2] . To fabricate such a high-quality semiconductor-based radiation detector, high-quality and high-purity semiconductor single crystals are needed. In addition, materials consisting of high atomic number elements are needed due to the higher probability of an incoming radiation beam interaction with valence electrons [3] . In this regard, a TlBr

Microstructural, optical and electrical properties of Cl-doped CdTe single crystals

1 Introduction CdTe is of considerable technological importance for use in semiconductor-based radiation detection applications, such as medical imaging and homeland security fields. The fabricated CdTe radiation detectors can be operated at room-temperature due to the favorable band gap (1.44 eV) and have been researched by various groups [ 1 – 7 ]. High resistivity is required for any semiconductor material to be used in realizing high-performance radiation detectors. Because high bias voltage is needed to improve the charge collection efficiency of

Charged projectile spectrometry using solid-state nuclear track detector of the PM-355 type

Abstract

To use effectively any radiation detector in high-temperature plasma experiments, it must have a lot of benefits and fulfill a number of requirements. The most important are: a high energy resolution, linearity over a wide range of recorded particle energy, high detection efficiency for these particles, a long lifetime and resistance to harsh conditions existing in plasma experiments and so on. Solid-state nuclear track detectors have been used in our laboratory in plasma experiments for many years, but recently we have made an attempt to use these detectors in spectroscopic measurements performed on some plasma facilities. This paper presents a method that we used to elaborate etched track diameters to evaluate the incident projectile energy magnitude. The method is based on the data obtained from a semiautomatic track scanning system that selects tracks according to two parameters, track diameter and its mean gray level.
