Description
The LANSCE accelerator facility has been in operation for 50 years performing important scientific support for national security. The unique feature of the LANSCE accelerator facility is multi-beam operation, delivering beams to five experimental areas. To reduce long-term operational risks and to realize future beam performance goals in support of the laboratory missions, we develop a novel high-brightness Front End injector. Proposed injector includes two independent low-energy transports for H+ and H- ions merging beams at the entrance of a single RFQ. These beamlines also perform preliminary beam bunching before RFQ. The challenge of the present project is associated with simultaneous acceleration of protons and H- ions with multiple beam flavors in a single RFQ, which has never been done before. Proposed injector must provide better than existing beam parameters while beam intensity is supposed to be increased by a factor of two and injection energy is reduced from 750 keV to 100 keV. The paper discusses details of beam physics design and presents injector parameters.
