Author(s) : SALERNO L. J., SPIVAK A. L., KITTEL P.
Type of article: Article
Summary
Two all-metal demountable cryogenic seals with an outside diameter of 36.6 mm, inside diameter of 27.2 mm and thickness of 0.51 mm were leak tested at room temperature (300 K), liquid-nitrogen temperature (21 cycles at 77 K), liquid-helium temperature (9 cycles at 4.2 K) and superfluid-helium temperature (4 cycles at 1.6 K). Each seal was mounted and demounted for 13 cycles. Leak rate measurements at all temperatures showed no detectable leak above the helium background level during testing.
