Indium and Vacuum Seals

We are going to use indium to make the vacuum seals on the SPARO dewar in order to preserve the case vacuum in the antarctic cold. There are a wide range of possibilities for the geometry of indium seals. Seals can be made between two flats, between a flat and a groove, or between a tooth and a groove. Furthermore, the geometry of the groove can be rectangular or triangular. Below are links to documents with information about indium seals.
