Abstract
Thin foils of Havar† have frequently been used as windows to separate a high pressure gas target from the vacuum system of the accelerator. This cobalt-based alloy is non-magnetic, corrosion resistant and has unusually high mechanical strength and resistance to fatigue. Tensile strength as high as 2.5 × 109 for the cold reduced and heat treated alloy have been reported.
