As I have stated before<\/a>, CapeSym SrI2<\/sub>(Eu)<\/a> scintillation detectors mounted on a silicon photomultiplier (SiPM) are characterized by high resolution and compact form factor. These detectors are easy to work with: they do not require high bias voltage (only 30V for power) and contain a built-in TMP451 sensor for PMT temperature monitoring, which could be used to compensate for thermal drift in the detector calibration.<\/p>\n\n\n\n

In this blog post I am going to evaluate a CapeSym SC-14x25c-SiPM-T detector, which has a 14 x 25 mm SrI2<\/sub>(Eu) scintillation crystal mounted on a silicon photomultiplier \u2013 Fig. 1. The wiring of the SC-14x25c-SiPM-T detector is the same<\/a> as for the SC-14x2c-SiPM-T detector.<\/p>\n\n\n\n

To evaluate the detector performance I have connected the detector signal to a PicoScope 4262 16-bit ADC via a 50-Ohm pull-down adapter and captured a variety of spectra using the PulseCounter software<\/a>. The signal acquisition frequency was 5 MHz with 10 MHz bandwidth. Useful signal range was 200 mV.<\/p>\n\n\n\n

The captured 137<\/sup>Cs, 133<\/sup>Ba, 57<\/sup>Co, 241<\/sup>Am, uranyl and 60<\/sup>Co spectra are shown on Fig. 2-7 respectively. The measured resolution was 2.9% FWHM @ 662 keV, 4% @ 386 keV, 6.6% @ 122 keV, 8.4% @ 60 keV, and 2.3% @ 1173 keV.<\/p>\n\n\n\n

Conclusion<\/h2>\n\n\n\n

CapeSym SC-14x25c-SiPM-T detector is characterized by good-sensitivity and high-resolution. The detector is compact, easy to work with and relatively inexpensive (~$1,300), which makes it very well suited for a broad range of spectroscopy applications.<\/p>\n\n\n\n

ScintiClear material is far superior than NaI(Tl) in terms of resolution and is in fact practically on par with the top of the line lanthanum bromide<\/a> detectors.<\/p>\n\n\n\n

ScintiClear detectors are 2-3 times cheaper than lanthanum bromide at the equivalent crystal size, which makes them particularly attractive.<\/p>\n","protected":false},"excerpt":{"rendered":"
