Description
A capillary plate (CP) gas detector with fibre optics plate (FOP) filled with
argon gas mixture and pure xenon gas has been successfully operated as a gas
scintillation proportional counter. Gas gains of up to 104 can be achieved with
these gas mixtures. Scintillation light simultaneously 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 with the above gas mixtures.
Successful operation with these gas mixtures has allowed us to realize a novel
imaging device with a CP for medical imaging, cellular function analysis, and X-ray
imaging.
