A relatively high activity 137 Cs source was placed close to the detector, producing a very large count rate, and yielding the spectrum below.
Energy Calibration of Germanium Gamma Ray Detectors This article will now detail the typical processes employed in gamma ray spectroscopy. This is used to prevent bots and spam. This article will now detail the typical processes employed in gamma ray spectroscopy. Ultimately, I used some of these skills later though. The same is true at 1324 keV for the summing of two cesium gamma rays.
This is used to identify particular browsers or devices when the access the service, and is used for security reasons. Five of the peaks were tagged in the MCA with their previously determined, known energies, thus calibrating the energy scale of the equipment. At around 40 keV, a number of x-rays were detected in the europium spectrum.
In order to use gamma rays safely, the source and energy of their emission must be determined. It was nice to get an experience of more than one type of detector.
An x-ray escape peak is also evident in the spectrum of 57 Co, which has many low-energy gamma rays. Gamma ray detectors are made from semiconductor materials, which contain atoms with orbiting electrons that can easily absorb the energy of a passing gamma ray.
A second contributor is incomplete charge collection, which increases with energy because more charge needs to be collected in the detector.
The small band-gap requires the detector to be cooled to prevent noise from leakage current. The width of the annihilation peak is uncharacteristically large.
Energy Resolution The percentage energy resolution is calculated using: The quantity C t is the total number of counts recorded per unit time, integrated over the whole spectrum. Nuclear physics discoveries utilizing gamma ray detectors continue to be made, and this trend looks set to continue well into the future.What Is Gamma Ray Spectroscopy?
