Thermally assisted recovery of low energy electron beam irradiation induced optical degradation of GaN

In this paper, we present our studies on thermally assisted recovery of low energy electron beam induced optical degradation of gallium nitride. A clear reduction in MOVPE grown GaN band-to-band photoluminescence intensity induced by low energy electron beam irradiation has been found before. Partial recovery of the band-toband emission was observed after annealing in both H2 and N2 ambient, at...

Electron beam central axis depth dose measurements.

Central axis depth dose measurements were made by the Radiological Physics Center on over 70 electron-producing machines used in radiation therapy. These data were consistent for each machine model and nominal energy. However, the data show that depth dose relations can vary significantly among different machine models for electron beams having the same nominal energy. Analysis shows that both ...

Investigation of the Effect of Electron Beam Different Doses on Optical Dissipation in Fiber Optic

Measurement of ionizing radiation in various fields, such as environmental safety, industrial detection processes, radiation protection and medical is very important. Radiation dosimetry plays an important role in determining the amount of energy absorbed and the effects of radiation. Recent optical fiber sensors have been shown to be radiation dosimeters. Our goal here is to investigate the ef...
