Lumped Ultra-High Vacuum Pumps Based on Non-Evaporable Getters

Lumped vacuum pumps based on non-evaporable getters are widely used in vacuum systems of charged particle accelerators. This type of pump will be used in the 4+ generation synchrotron at the Siberian Ring Source of Photons shared resource center. Prototypes of getter pumps with hydrogen pumping speeds of 300, 600, 900, and 1300 L/s are being manufactured and tested at the Budker Institute of Nuclear Physics. The designs of pumps are described, along with results from their tests.
