TI - High-Brightness RFQ Injector for LANSCE Multi-Beam Operation J2 - Proc. of LINAC2022, Liverpool, UK, 28 August-02 September 2022 CY - Liverpool, UK T2 - International Linear Accelerator Conference T3 - 31 LA - english AB - The unique feature of the LANSCE accelerator facility is multi beam operation. Accelerator delivers 100 MeV H⁺ and 800 MeV H⁻ beams to five experimental areas. The LANSCE front end is equipped with two independent injectors for H⁺ and H⁻ beams, merging at the entrance of a Drift Tube Linac (DTL). Existing Cockcroft-Walton (CW) - based injector provides conservation of high value of beams brightness before injection into DTL. To reduce long-term operational risks and support beam delivery with high reliability, we designed an RFQ-based front end as a modern injector replacement for the CW injectors. Proposed injector includes two independent low-energy transports merging beams at the entrance of a single RFQ, which accelerates simultaneously both protons and H⁻ ions with multiple flavors of the beams. Paper discusses details of beam physics design and presents injector parameters.
