Fast Neutron Detector Using PIN-type Silicon Photodiode.

Properties 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 ...

Double-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...

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...

Characterization Of Pin Diode Silicon Radiation Detector

Bhabha atomic research centre has been exploring some of the unique features of silicon detector in a variety of nuclear structure experiment using high-energy photons and heavy ions projectiles. Current experimental application make use of large area silicon detector with depletion thickness of ~150-1000 μm. The low cost silicon detector shows excellent energy and position resolution. In this ...
