Feasibility of liquid-metal vacuum seals
Overview & Synopsis
A basic component of any ultrahigh-vacuum system is a seal capable of isolating a test chamber from its higher pressure surroundings. Two of the most common vacuum seals now in use are the elastomer O-ring seal and the metallic shear seal. The former has the problem of outgassing and gas permeation; the latter requires a large force per unit seal-length to maintain the sealing action. The search for a seal which would provide minimal virtual and real leak rates in a chamber, without requiring a large force to consummate the seal, led to investigation of a liquid-metal seal.
