(A) Digital render of the vacuum flange structure with components for vacuum sealing. The test piece was designed with a top hat profile with a diameter of 70 mm and indium sealed onto a stainless steel flange. The stainless steel flange had a bore hole of 30 mm in the centre and 6 M6 tapped holes to apply pressure to the indium seal. Once sealed the DN40CF flange is attached to the chamber using a standard copper gasket. The holes in test piece are compatible with a DN40CF flange. (B) The DN40 CF flange and test piece prior to Assembly.
