Abstract

The invention discloses a beta/internal conversion electronic vacuum measuring device, and relates to the technical field of energy spectrum measurement. The device comprises an SDD detector and a tank body, an X-ray silicon drift probe sleeve of the SDD detector is provided with a fastening pressing cap, the X-ray silicon drift probe sleeve of the SDD detector is provided with a first O-shaped sealing ring and a space ring, and the tank body is internally provided with a cavity. A through hole is formed in the middle of the top of the tank body, a tubular tank opening connected with the through hole in a sealed mode is fixedly formed in the through hole, air holes are symmetrically formed in the top of the tank body, Swagelok quick connectors are arranged in the air holes, and a second O-shaped sealing ring is fixedly connected to the outer edge of the bottom of the tank body. A windowless sealing design between a sample to be detected and the SDD detector is achieved, attenuation orabsorption of beta particles/internal conversion electrons by air or other media is avoided, and the vacuum sealing performance of the device is remarkably improved in the mode that the fastening pressing cap applies pressure to the multiple layers of space rings and the O-shaped sealing rings.

Description

technical field [0001] The invention relates to the technical field of energy spectrum measurement (radiation measurement field), in particular to a β / internal conversion electronic vacuum measurement device. Background technique [0002] The measurement of β / internal conversion electron spectroscopy is an important part of nuclear radiation measurement. For radionuclides with relatively large internal conversion coefficients or pure β decay, or when it is difficult to implement measurements using γ-ray spectroscopy (such as on-site inspections), β / internal conversion electron spectroscopy measurement will be a good method. alternative method. The advantages of β / internal conversion electron spectroscopy: no heavy shielding is required; internal conversion electrons have obvious characteristic peaks; low-energy background interference is very small. β / internal conversion electrons are charged particles, which are easy to interact with air or other media, and the range is v...
