A liquid-helium cooled large-area silicon PIN photodiode x-ray detector
An x-ray detector using a liquid-helium cooled large-area silicon PIN photodiode has been developed along with a tailor-made charge sensitive preamplifier whose firststage JFET has been cooled. The operating temperature of the JFET has been varied separately and optimized. The xand γ-ray energy spectra for an Am source have been measured with the photodiode operated at 13 K. An energy resolutio...
متن کاملDouble-Layer Silicon PIN Photodiode X-Ray Detector for a Future X-ray Timing Mission
A double-layer silicon detector consisting of two 500μm-thick silicon PIN photodiodes with independent readouts was mounted in a vacuum chamber and tested with X-ray sources. The detector is sensitive from 1–30 keV with an effective area of 6 mm. The detector performs best at −35 ◦C with an energy resolution of 220 eV (FWHM, full width at half maximum) at 5.9 keV, and is able to operate at room...
متن کاملComparison of the current of UV ray radiation on PIN Silicon photodiode and Gallium Arsenide
The high-energy UV ray radiation on PIN Silicon photodiodes reduces the optimal parameters of these photodiodes. In this paper, by representing a model, we compare the effect of UV dose on the bright current in these two types of photodiodes and confirm the analytic relationships in order to simulate a model with the help of the Silvaco- Atlas software. In this model, Silicon photodiodes and Ga...
متن کاملX-ray spectrometry with Peltier-cooled large area avalanche photodiodes
Performance characteristics of the response of a Peltier-cooled large-area avalanche photodiode are investigated. Detector gain, energy linearity, energy resolution and minimum detectable energy are studied at different operation temperatures. Detector energy resolution and lowest detectable X-ray energy present a strong improvement as the operation temperature is reduced from 25 to 15 C and sl...
متن کاملProperties of a PIN photodiode as a neutron detector
The properties as a neutron detector of a silicon photodiode of type Hamamatsu S3590-02 in conjunction with a multi-channel analyser Alphatron-3C were investigated in an Am-Be calibration field at the department of nuclear engineering at the University of Madrid. Since the photodiode is sensitive to charged particles, we covered it with two types of converters to enable its response to thermal ...
