Abstract
The development of an ambient pressure MeV SIMS ion beam analysis capability at the Surrey Ion Beam Centre has necessitated the development of a system to protect the vacuum integrity of the main 2 MV tandem particle accelerator. The development and operating characteristics of a fast acting vacuum isolation valve based on the principle of an induction coil are reported and shown to be suitable for the intended application.
