High-Resolution Spectroscopy with LaBr3

Posted on January 21, 2025January 21, 2025 by maxfomitchev

Cerium-doped lanthanum bromide - LaBr3(Ce) - scintillators offer better resolution and greater stopping power compared to conventional thallium-doped sodium iodine - NaI(Tl) - scintillators. A typical lanthanum bromide scintillator achieves a 2.5% FWHM @ 662 keV resolution compared to a ... Read More

Posted on November 22, 2023 by maxfomitchev

In this post I describe how to use a Bicron 1.5M2.25/1.5L gamma detector with the MCA-LITE. The experimental setup is shown on Fig. 1. Fig. 1. MCA-LITE with Bicron 1.5M2.25/1.5L gamma detector. The recommended MCA-LITE preset is as follows: Sampling ... Read More

Setting Up Automated Nuclear Lab for Gamma Spectroscopy

Posted on August 3, 2023November 1, 2023 by maxfomitchev

In this article I am going to demonstrate how to set up and use an MCA-PRO16 2CH (which is a member of the ANL family) with a low-energy gamma probe. Hardware Setup For low-energy gamma spectroscopy I chose a Bicron ... Read More

High-Precision Spectroscopy with PGT HPGe

Posted on February 23, 2023February 23, 2023 by maxfomitchev

High purity germanium detectors are the highest resolution gamma detectors available. The only disadvantage is the need for cryogenic cooling, which is traditionally accomplished using a liquid nitrogen Dewar or more recently using a mechanical cooler such as Ortec X ... Read More

Using Canberra 1510 with PulseCounter

Posted on July 15, 2022October 20, 2022 by maxfomitchev

Canberra 1510 is an older but nevertheless very nice and useful module that combines a high-voltage bias power supply (0 to 2kV, positive or negative polarity) with an adjustable gain preamp and a shaping amplifier. In other words, this unit ... Read More

Ortec digiBASE-E Gamma Spectrometer

Posted on July 2, 2022October 20, 2022 by maxfomitchev

Ortec digiBASEE-E is very cool and compact gamma spectrometer integrated with 14-pin PMT base, and it comes with a very detailed and complete manual. To operate the spectrometer one must have a scintillation detector with a 14-pin PMT and a ... Read More

Gamma Calibration Sources

Posted on June 2, 2021October 20, 2022 by maxfomitchev

When working with gamma spectroscopy it is very important to have a calibration source. Why do you need one? The answer is quite simple: to calibrate your gamma spectrometer prior to acquiring spectra. Calibration Drift It is true that most ... Read More

Cremat Charge-Sensitive Preamps and Shaping Amplifiers

Posted on January 17, 2021October 20, 2022 by maxfomitchev

Detector Signal Processing Most x-ray and gamma detectors produce a current pulse that has to be converted to a voltage pulse that can be measured and analyzed in order to build a spectrum. Classic signal processing approach involves charge integration ... Read More

CapeSym ScintiClear SC-14×25 SiPM Gamma Detector

Posted on November 25, 2020October 20, 2022 by maxfomitchev

As I have stated before, CapeSym SrI2(Eu) 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 ... Read More

Low-Energy SDD X-Ray Spectrum of a Co-57 Source

Posted on November 17, 2020October 20, 2022 by maxfomitchev

I have connected a Ketek AXAS SDD detector (Fig. 1) to an MCA-PRO 16 system and calibrated the spectrometer using a Fe-55 source (Fig. 2) purchased from Imagesco. Fig. 1. Ketek AXAS SSD detector. Fig. 2. 55Fe and 57Co calibration ... Read More
