||W55 - Basic Gamma Spectroscopy with a NaI(Tl) Detector
||Simple gamma spectroscopy is easily demonstrated for science students and they find such demonstrations intriguing. When given the opportunity to perform some spectroscopy on their own, we find there are many issues with instrumentation and data interpretation that have escaped them in their previous laboratory work. The meaning of calibration, the effects of small nonlinearities, the operation of high-voltage electronics, pulse amplification, and analog to digital conversion are all important issues to be explored. Even reading and commenting on a gamma energy spectrum fools some good students. We will work through a half-life measurement and counting statistics measurements, after calibration the instrument.
