Abstract

A bakeable ultrahigh-vacuum valve, with a coarse screw thread and conical springs, eliminates slip common to differential thread valves and reduces the bakeout-induced compression and release of the valve disk. The straight-through valve isolates a polarized electron source from gas scattering regions and maintains precision electron optical paths using a right-angled insertable electron lens.
