Recently a PIN photodiode is more widely used than a conventional PMT, because it requires less bias to operate it and it is very compact. A PIN photodiode was designed and fabricated for a matching with a CsI(Tl) scintillator in consideration of low leakage current and high biasing voltage. Leakage current and spectral response were measured with the fabricated PIN photodiode as preliminary tests. A CsI(Tl)/PIN photodiode radiation detector was also fabricated and about 10.4% FWHM was achieved at 662 keV gamma-ray. In this study, characteristics of a fabricated PIN photodiode and a CsI(Tl)/PIN photodiode radiation detector were presented. Several important aspects to consider in the fabricationof a SiPIN photodiode radiation detector are also addressed.
