	As part of the Los Alamos Neutron Science Center (LANSCE) the Ion Source Test Stand (ISTS) is a flexible, stand-alone facility used for H⁻ ion beam source development and studies of low energy beam transport. It consists of a surface convertor ion source with a multi-cusp permanent-magnet plasma confinement structure, an 80-kV high-voltage electrostatic extraction column, a low-energy ion beam transport line, and beam phase-space diagnostics. After resolving several technical issues, the ISTS was successfully restarted during the summer of 2012. Since then we have performed several long duration experiments. A development program is ongoing with the goals of improving source performance (reliability, availability, increased current, etc.) and beam transport efficiency (beam neutralization at low energy, beam dynamics with/without noble gas injection, etc.). Several enhancements to performance are being investigated in order to achieve a forthcoming upgrade requirement of LANSCE operations in 2014: beam current of 16-18 mA, 120-Hz operation at a duty factor of 10% and a source lifetime of 28 days. We present recently obtained results and a short description of the ISTS apparatus.

As part of the Los Alamos Neutron Science Center (LANSCE) the Ion Source Test Stand (ISTS) is a flexible, stand-alone facility used for H⁻ ion beam source development and studies of low energy beam transport. It consists of a surface convertor ion source with a multi-cusp permanent-magnet plasma confinement structure, an 80-kV high-voltage electrostatic extraction column, a low-energy ion beam transport line, and beam phase-space diagnostics. After resolving several technical issues, the ISTS was successfully restarted during the summer of 2012. Since then we have performed several long duration experiments. A development program is ongoing with the goals of improving source performance (reliability, availability, increased current, etc.) and beam transport efficiency (beam neutralization at low energy, beam dynamics with/without noble gas injection, etc.).
