摘要：

Here we introduce a simple, low-cost, contamination-free, and highly reliable technique for sealing an ultra-high vacuum (UHV) cryostat by using cryogenically freezable liquid. We demonstrate it by sealing an UHV cryostat with dry leaks in the high vacuum range; ethanol was utilized to fill and block the leakage pathways through the subsequent in situ solidification by LN2. The seal is reversible and can be maintained as long as the cryostat is kept at cryogenic temperature. (C) 2015 AIP Publishing LLC.
