Abstract
Powerful cw proton linear accelerators (100 mA at 0.5–1.0 GeV) are being proposed for spallation neutron‐source applications. A 75‐keV, 110‐mA dc proton injector using a microwave ion source is being tested for these applications. It has achieved 80‐keV, 110‐mA hydrogen‐ion‐beam operation. Video and dc beam‐current toroid diagnostics are operational, and an EPICS control system is also operational on the 75‐keV injector. A technical base development program has also been carried out on a 50‐keV injector obtained from Chalk River Laboratories, and it includes low‐energy beam transport studies, ion source lifetime tests, and proton‐fraction enhancement studies. Technical base results and the present status of the 75‐keV injector will be presented.Keywords
