Abstract

The invention provides a tritium gas online measuring device capable of continuously operating, and belongs to the technical field of tritium gas detection devices. The device comprises two closed detection sealing chambers and a sample sealing chamber, wherein a vacuum coupling cavity is arranged between the sample sealing chamber and each of the two detection sealing chambers, a tough-induced radiation target film, a heating layer capable of heating the tough-induced radiation target film and a sample chamber shell are sequentially arranged on a wall plate, close to one side of any detection sealing chamber, of the sample sealing chamber from inside to outside, the tough-induced radiation target film is made of a high-atomic-coefficient metal which has high X-ray yield after interacting with beta rays, an X-ray detector is arranged in the detection sealing chamber, the enclosure piece of the vacuum coupling cavity comprises a component which allows X-rays to enter the detection sealing chamber from the sample sealing chamber, and a switching structure which comprises a partition plate and can slide in the sample sealing chamber along the connecting line direction of the two detection sealing chambers is arranged in the sample sealing chamber. The device has the advantages of continuous and high-precision detection of the tritium amount and the like.

Description

technical field [0001] The invention belongs to the technical field of tritium gas detection devices, and relates to a tritium gas online measurement device capable of continuous operation. Background technique [0002] The beta ray released during the spontaneous decay of tritium interacts with metal materials to produce low-energy X-rays, and tritium can be measured indirectly by measuring X-rays. Because tritium does not contact with the detector, it can prevent tritium from remaining on the detector and reduce the memory effect. This feature makes it widely used in online measurement of high-concentration tritium gas places. [0003] Common techniques used for on-line monitoring of gaseous tritium include ionization chambers, gas chromatography, and mass spectrometers. Ionization chambers can be used online, but their applications are limited by their sensitivity to gas chemical composition, strong memory effects, need for periodic recalibration, and need to operate und...
