✦ Synopsis

A capillary plate (CP) gas detector with fiber optic plate (FOP) has been successfully operated as a gas scintillation proportional counter. A thin film of indium tinoxide (ITO) was used for the transparent electrode of the CP. Scintillation light emitted during the development of electron avalanches can be observed through the FOP using a photomultiplier tube (PMT) and an optical imaging system, which consists of a CP gas detector and a cooled CCD camera coupled to lens optics. Using this optical imaging system, clearer images of X-rays have been obtained. Successful operation with the CP gas detector and the FOP has allowed us to realize a novel imaging device for medical imaging, cellular function analysis, and X-ray imaging.
