High Reliability, Long Lifetime, Continuous Wave H- Ion Source Design

摘要

Phoenix Nuclear Labs has completed the preliminary design of a CW negative hydrogen ion source that will exceed the requirements of proposed Intensity Frontier particle accelerator injectors. The design pairs proven microwave ion source technology as a source of hyperthermal neutral hydrogen atoms and a cesium converter for negative hydrogen ion production similar to that which is used at the Spallation Neutron Source. The anticipated result will be a CW negative hydrogen ion source capable of generating a low emittance beam of at least 10 mA of H- ions with a source lifetime that should be at least several months, if not longer. Next steps include finalizing the source design after further input from Fermilab scientists, procuring all required hardware, and assembling the prototype ion source for testing.
