62. Lifetime and Emittance Optimization for High Intensity RF-driven H- Source

Weidong Chen (Institute of high energy physics, Chinese Academy of Sciences.)

9/23/26, 10:10 AM

Invited

Lifetime and emittance are two key parameters for an RF-driven H$^-$ source used in high-power proton accelerators. At the China Spallation Neutron Source (CSNS), we have developed a high-intensity RF-driven H$^-$ ion source with an external antenna structure, capable of generating a beam current exceeding 60 mA. To extend the lifetime of the ion source, improvements have been made over the...

43. Design choices, implementation and status of the PIP-II Warm Front End

Lionel Prost (Fer)

9/23/26, 10:35 AM

Invited

The Proton Improvement Plan II (PIP-II) at Fermilab is a program of upgrades to the injection complex currently under construction. A major component is a new 2 mA, 800 MeV H- CW-compatible superconducting linac (a.k.a. Linac2), initially operating in a beam pulse mode. Installation of the Warm Front End (WFE) in the Linac2 facility is underway. Beam commissioning is planned to start in summer...

161. Operational Experience with a Positive / Negative Filament Ion Source

Brian Roeder (Cyclotron Institute, Texas A&M University)

9/23/26, 11:00 AM

Invited

A filament-driven ion source for hydrogen and helium ion beams, capable of producing both positive and negative ions, has been in operation at the Cyclotron Institute at Texas A&M University since early 2024. The ion source, manufactured by D-Pace, replaced an older filament ion source that only produced H- and D- ions. The +/- filament ion source has been installed on the vertical injection...

69. Long-lived high-power negative ion beam accelerations update from the CRAFT NNBI test facility

Dr Jianglong Wei (Institute of Plasma Physics, Chinese Academy of Sciences)

9/23/26, 11:45 AM

Invited

The Comprehensive Research Facility for Fusion Technology (CRAFT) is dedicated to developing core key technologies for future fusion reactors, which incorporates a Negative Ion Source Neutral Beam Injection (NNBI) test facility. The CRAFT NNBI test facility consists of two core test stands: the Hefei Open-facility for Negative-ion Source Research (HONOR), which focuses on experimental...
