Abstract
An X-ray detector using a liquid-helium cooled large-area silicon PIN photodiode has been developed along with a tailor-made charge sensitiv e preamplifier whose first-stage JFET has been cooled. The operating t emperature of the JFET has been varied separately and optimized. The X - and gamma-ray energy spectra for an Am-241 source have been measured with the photodiode operated at 13 K. An energy resolution of 1.60 ke V(FWHM) has been obtained for 60-keV gamma rays and 1.30 keV (FWHM) fo r the pulser. The energy threshold could be set as low as 3 keV. It ha s been shown that a silicon PIN photodiode serves as a low-cost excell ent X-ray detector which covers a large area at 13 K.
