      Abstract:

      A new vacuum seal for a rectangular flange used in r.f.   equipments, was developed. The vacuum seal consists of a recess   with a flat surface, machined into a rectangular flange, a   rectangular metal gasket with a raised projection on one face,   and a mating flange with a recess and raised projection. No leak   greater than 1 × 10−10 Pa m3/s was found in   leak tests, before and after baking cycles (100 °C, 12 h).
