X-ray image have been developed for medical and non-destructive inspection, and higher resolution and larger area detectors are required due to the development of technology. Therefore, in this study, the spatial resolution of a scintillation type image detector, which is an indirect conversion type X-ray image detector can be easily enlarged has been improved. The cause of lowering the...
Fusion reactions, such as the D-D and D-T reactions, can be used to produce neutrons in smaller devices than conventional neutron sources such as nuclear reactors and large accelerators. Compared to conventional methods, this neutron source enables to make imaging devices smaller and more convenient.
The Small-scale neutron imaging device is consisted of a neutron source, detectors, and other...
Thallium bromide is a compound semiconductor with high atomic number and density and wide bandgap. Therefore, thallium bromide has potential as a direct conversion type radiation detector that can operate at room temperature.
One application for semiconductor detectors is for low-energy X-ray applications such as mammography and pathology, where the high stopping power of thallium bromide...
X-ray imaging technology has applications in medicine, nondestructive testing at industrial sites, and security inspections at airports.
Today, semiconductor detectors are widely used as radiation detectors. Because semiconductor detectors convert X-rays directly into electric charge, they are considered to have higher spatial resolution than scintillator-type detectors, which convert X-rays...
CdTe has been used as radiation detectors at room temperature. Impurity doping of CdTe has been considered difficult because it requires high temperature heat treatment and characteristics are degraded. However, the laser doping method that we have recently developed is overcoming this problem. When doping semiconductors, not all dopants act as donors or acceptors, and some of them become...
