Kromek SPEAR CZT is a compact gamma detector with the useful energy range of 30 keV to about 300 keV, priced just under $2,000 US dollars - Fig. 1. Fig. 1. Kromek SPEAR CZT gamma detector. Although the manufacturer-declared energy ... Read More

The Rich Physics of Cs-137 Gamma Spectrum

Posted on October 24, 2020January 23, 2025 by maxfomitchev

The process of beta decay is an extremely fascinating phenomenon. I cannot think of any other physical process that is so rich in fundamental physics. Please allow me to elaborate. Recommended Tools MCA-PRO (dual-instrument multichannel analyzer, pulse processor, power supply); ... Read More

Saint Gobain Enhanced Lanthanum Bromide Detector

Posted on September 13, 2020October 20, 2022 by maxfomitchev

Lanthanum Bromide Advantage Lanthanum bromide scintillators are gaining popularity due to their superior resolution properties. Typical resolution of a LaBr3(Ce) scintillation detector @ 661.7 keV is between 2.5 and 3.5% depending on manufacturer and crystal grade. Thus, LaBr3(Ce) detector resolution ... Read More

Background Gamma Spectrum

Posted on May 13, 2020October 20, 2022 by maxfomitchev

Here is a high-energy background gamma spectrum I have captured for 10 hours using GAMMA-PRO 5" system - Fig. 1. I had to lower detector bias to 600V to prevent the highest energy gamma events from clipping. Fig. 1. High-energy ... Read More

Gamma Spectrometry with CZT

Posted on May 1, 2020October 20, 2022 by maxfomitchev

Using eV Products CdZnTe (CZT) solid-state compact gamma detector (Fig. 1) and MCA-PRO 16 I have acquired the following calibration spectra: Cs-137, Co-57, and Ba-133 (Fig. 2 - 4). I was getting better resolution at higher bias voltages, so I ... Read More

X-Ray Spectrometry with Bicron 1XMP.040B

Posted on April 29, 2020October 20, 2022 by maxfomitchev

Bicron 1XMP.040B is a low-energy gamma (e.g. x-ray) NaI(Tl) detector similar to FIDLER, except that it is much smaller in size. The scintillator crystal dimensions are 1" by 1 mm, and the detector cross-section is shown on Fig. 1. Fig. ... Read More

Low-Energy Gamma Detection with FIDLER

Posted on April 22, 2020October 20, 2022 by maxfomitchev

FIDLER stands for Field Instrument for the Detection of Low Energy Radiation. Typical FIDLER detector contains a 5" diameter x 0.06" thick NaI(Tl) "pancake" scintillator mounted on a 5" photomultiplier tube protected by a thin (0.01") beryllium window - Fig. ... Read More
