摘要

一种损耗面积非常小的铟密封的改进版本，其中使用纯in焊料代替纯in焊丝，已经在直径20mm的玻璃窗上进行了试验。事实证明，这种密封对4.2K的液氦是真空密封的。使用STYCAST 2,850 gt的10mmφ蓝宝石窗户密封也在4.2K下成功测试。

A Test of Modified Indium Seal of a Window at Liquid Helium Temperature(Physics)

A modified version of an indium seal with a very small loss area, in which pure In solder is used instead of pure In wire, has been tried for a glass window of 20mm in diameter. It has turned out that this seal is vacuum tight against the liquid helium at 4.2K.A seal of a 10mmφ sapphire window with STYCAST 2, 850GT was also successfully tested at 4.2K.
