Anti - Cosmic Ray High Purity Germanium Gamma Spectrometer
Product details

. Product Introduction

TK-103 anti-cosmic ray high purity germanium measurement system consists of HPGe main detector, inner shield, plastic scintillator shield anti-cosmic ray detector and external shielding room, anti-cosmic ray electron module, multi-channel analyzer, energy spectrum analysis Software, liquid nitrogen re-condensing refrigerator and other components; the main detector chamber is filled with nitrogen to further reduce the contribution of radon daughter to the background and cadmium sheet is used to reduce the contribution of thermal neutrons to the background. Figure 1 shows the comparison between measurement results made through the anti-cosmic ray spectrometer and the general low background spectrometer. Figure 2 shows the schematic diagram for the anti-cosmic ray spectrometer.
