Abstract

LBNL designed and built the Frontend for the Spallation Neutron Source, including its H^- source and Low-Energy Beam Transport (LEBT). This paper discusses the performance of the H^- source and LEBT during the commissioning of the accelerator, as well as their performance while ramping up the SNS beam power to 540 kW. Detailed discussions of major shortcomings and their mitigations are presented to illustrate the effort needed to take even a well-designed R&D ion source into operation. With these modifications, at 4% duty factor the LBNL H^- source meets the essential requirements that were set at the beginning of the project.
