Special Issue on Room-temperature-operation Solid-state Radiation Detectors
Guest Editor: Toru Aoki (Shizuoka University)
We grew a Cd0.95Mn0.05Te0.98Se0.02 (CMTS) semiconductor, which is the next-generation gamma-ray detector operating at room temperature, via the Bridgman method. During Br etching, one of the fabr ... Read More
In this paper, we report on the electrical stability of cadmium telluride (CdTe) detectors with metal-insulator-semiconductor (MIS) structures using a native oxide layer. Although such electrode ... Read More
TlBr has high detection efficiency and energy resolution and is also considered a semiconductor detector material that can be operated at room temperature. We have developed and improved a system ... Read More
LiZnBO3:Mn was synthesized to develop a new material for neutron imaging. Small pieces of colorless, transparent single crystals were obtained by the vertical Bridgman technique, although a large ... Read More
We attempted to measure α-particles emitted by radioactive substances present in nitric acid using a single-crystal CVD diamond radiation detector, which allows for the acquisition of detailed e ... Read More
The high-temperature operation of a diamond radiation detector was demonstrated with charge collection efficiency at temperatures up to 500 °C. The detector operated steadily even at high temper ... Read More
As part of the development of thallium bromide (TlBr) semiconductor detectors, impurity doping into TlBr by the thermal diffusion method was attempted, along with the exploration of ohmic electro ... Read More
In this paper, we discuss the development of a diamond detector element for a criticality proximity monitoring system, which is essential for the decommissioning of the Fukushima Daiichi Nuclear ... Read More
X-ray computed tomography (CT) is widely used as a nondestructive inspection technique in the medical, security, and industrial fields. The authors propose a method of visualizing the internal de ... Read More
A thallium bromide (TlBr) detector with four-channel readout electrodes was fabricated from a crystal grown by the traveling molten zone method from a zone-purified material for boron neutron cap ... Read More
