A removable cryogenic window for transmission of light and neutrons

A demountable, superfluid-tight window for the transmission of neutrons and light has been developed. A fluorocarbon polymer (Teflon) film is both the window and sealing gasket. Transmission of blue light and bursting pressure are measured for films of varying thicknesses.
