Abstract
The Los Alamos Neutron Science Center (LANSCE) 800 MeV accelerator facility uses a multicusp-field, surface production ion source to produce a H/sup -/ beam for delivery to the Proton Storage Ring (PSR) and to the Weapon Neutron Research (WNR) areas. The average current delivered to the short-pulse spallation target is nominally 70 /spl mu/A. One goal of the present PSR upgrade project is to increase the average beam current to 200 /spl mu/A. This will be accomplished by a combination of increased repetition rate (from 20 Hz to 30 Hz), upgraded PSR bunchers, and a brighter H/sup -/ ion source that is being designed to produce higher peak current with lower beam emittance. The present ion source and LEBT system were studied to investigate beam quality and performance at higher peak currents. Beam parameters from the ion source and in the LEBT at higher currents are compared to those for standard operating conditions.
