説明
To strengthen the thin window of a proportional gas flow counter which is capable to detect low energy β-ray such as tritium is described. The window film is made of alkyl-benzene whose thickness is extremely thin (0.15mg/cm2) and has large surface (30mm×150mm). In order to strengthen the window without increasing the thickness of the film, a latticed frame was installed to support the window film. Calculation for approximating of strengthening of the thin window was discussed. Mechanical strength of the window was estimated to withstand a pressure difference 66 times greater than that without the frame. It was also proved that the strength of the film by the pressure difference calculated agreed with that of experimental results with the accuracy of 10%. It is confirmed that the gas flow counter for measuring low energy β-ray developed in our laboratory, inspite of using the latticed frame, has identical counting efficiency without latticed frame.
