Abstract

The invention discloses a two-probe X-ray detection device based on coincident sampling. The two-probe X-ray detection device comprises a light tube base, a first probe, a second probe, a light tube collimator, a first collection device and a second collection device, a light tube is mounted on the light tube base and fixed on the same through a light tube shielding upper cover, a containing groove used for containing the light tube collimator is formed in the light tube shielding upper cover, the light tube collimator is fixed on the light tube, a detection window is formed at the top of the light tube shielding upper cover, the containing groove is communicated with the detection window, the first probe and the second probe are symmetrically arranged on the left and right sides of the light tube collimator, the first probe is connected with the first collection device, the second probe is connected with the second collection device, and the light tube is connected with either the first collection device or the second collection device. The two probes are adopted, wider energy spectrum diagrams can be acquired by applying coincident sampling technology, background interference is eliminated, and measuring results are more accurate while detection limit is lower.

Description

technical field [0001] The invention relates to a double-probe X-ray detection device based on coincidence sampling. Background technique [0002] The known spectrometers (including handheld, mobile, and desktop) are all designed with a single probe. This design has some shortcomings: with the increase of the actual count rate, the pulse superposition is serious, the dead time is high, and the detection accuracy is not ideal. ; The energy spectrum is narrow; background interference is inevitable; the measurement results are not accurate enough. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a dual-probe X-ray detection device based on coincidence sampling, which obtains a wider energy spectrum by using coincidence sampling technology, eliminates background interference, and makes the measurement results more accurate and the detection limit lower Low. [0004] In order to achieve the above object, the techni...
