Helium Leak Detector (for Leak and % Purity) – Forensics Detectors

WebA He-3 tube with just helium will show a distribution with the peak energy at 764 keV. Ideally, all of the energy of the reaction products ends up deposited in the gas of the detector. More typically, the ssion products collide with the wall of the tube, losing energy. The result is plateaus in the distribution. http://hiq.linde-gas.com/en/analytical_methods/gas_chromatography/thermal_conductivity_detector.html
