Description
Technical field
The present invention relates to radgas fields of measurement, meets radgas measuring chamber and X-ray detector probe is whole
Body is hermetically sealed, and does not have the measurement demand of sealing medium between detector probe and tested gas.
Background technique
In radgas fields of measurement, usually radgas to be measured is constrained in closed measuring chamber, and keep compared with
Good leakproofness.General radgas measuring chamber is designed with measurement window, i.e., between detector probe and tested gas
Sealing medium.In order to reduce the medium to X or gamma-ray attenuation effect, measurement window generally uses the aluminium alloy or carbon of low-density
Production, thickness 1mm or so.But if measurement object is the X-ray that energy only has tens of keV, this layer of measurement window can penetrate X
Line generates deep fades.The Si-PINX ray detector measurement radgas measuring chamber of this patent penetrates gas measurement room and X
The encapsulation of line detector integral sealing, does not have sealing medium between detector probe and tested gas, significantly reduces declining for X-ray
Subtract, improves measurement efficiency.In addition, X-ray detector and PIPS detector are installed in gas measurement room two sides respectively, has X and penetrate
Line and β ray coincidence measurement function.
Document comparative analysis shows that the country has no document report with the mutually isostructural device research of the invention and manufacturer
Road.
