Outline of Final Research Achievements

Fabrication of pixelized radiation detector composed with organic semiconductor material has been studied based on ink-jet printing technology. Fabrication parameters and kind of solvent were optimized to realize stable current output under irradiation of X-rays. Pixelized detectors with five sensing regions were fabricated and their applicability to radiation distribution measurements has been shown. Possibility of radiation energy estimation with the data measured by using current-output organic semiconductor detectors were evaluated. The results showed that, with conventional energy unfolding algorithm, it is possible to estimate radiation energy with this technique.
