The Spallation Neutron Source H(-) ion source is operated with a pulsed 2-MHz RF (50-60 kW) to produce the 1-ms long, ∼50 mA H(-) beams at 60 Hz. A continuous low power (∼300 W) 13.56-MHz RF plasma, which is initially ignited with a H2 pressure b

The Spallation Neutron Source (SNS), a large scale neutron production facility, routinely operates with 30-40 mA peak current in the linac. Recent measurements have shown that our RF-driven internal antenna, Cs-enhanced, multi-cusp ion sources inject

This paper describes the accomplishments of the SNS H− ion source, which delivers routinely ∼50 mA at a 5.4% duty factor with ∼99% availability, enabling 1 MW beams for neutron production with ∼90% availability. It discusses the need for incr

In experiments with RF saddle antenna surface plasma sources (SPS), the efficiency of H− ion generation was increased by up to a factor of 5 by plasma electrode “activation”, without supplying additional Cs, by heating the collar to high temper

The Spallation Neutron Source (SNS) at Oak Ridge National Laboratory reached 1‐MW of beam power in September 2009, and now routinely operates near 1‐MW for the production of neutrons. This paper reviews the performance, operational issues, implem

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
