Outline of Final Research Achievements

We aimed at large-area, bendable radiation detectors and worked on the development of a new structure detector applying organic TFT manufacturing technology. We conducted a quantum beam irradiation test to confirm the performance of the prototype element as a radiation detector. Initially, the S / N ratio was not good, and we could not distinguish between signal and noise. We have reduced the element size so that it can be installed close to the preamplifier, and also improved the preamplifier board. Although the signal of the heavy particle ion could be detected, the charge collection efficiency was still insufficient and it was not possible to observe the signal by α ray. In order to compare the charge collection efficiency of the device, we tried using blue LED light which can obtain a large detector signal. Signals were observed, and experimental conditions such as applied voltage to the device could be optimized.
