AB  - The Los Alamos Neutron Science Center operates with two 750 keV Cockcroft-Walton accelerators for simultaneous injection of H⁺ and H⁻ ion beams into a 800 MeV linear accelerator. The proton ion beam is produced using a duoplasmatron source and the H⁻ ion beam is formed with a cesiated, multi-cusp-field, surface converter ion source. An overview of ion injector status, recent low energy beam transport line optimizations and ion source performance improvements will be presented. To reduce long term operational risks and to improve existing LANSCE beam production for all facility users, new injector upgrades are underway: 1) replacing the H⁺ CW injector with a Radio-Frequency Quadruple accelerator and 2) increasing H⁻ ion beam brightness and extending source lifetime using the novel SNS RF negative ion source. The status of upgrade projects will be discussed.
