Abstract: The entrance windows and container body of the gas detector chambers used in high energy and intensity accelerators must be as thin as possible to minimise energy losses. Polyimide foils have high mechanical and chemical resistance, and as a consequence more and more they are being applied widely. Commercially available polyimide foils are 7-8 µm (1 mg/cm2) thick. The foils prepared by in-situ polymerisation can be as thin as 0.07 µm (~10 µg/cm2). The gas permeability of foils prepared by this method has been measured and the results are presented in this paper.
