39. H- Source Developments and Operation at CERN

Jean-Baptiste Lallement (CERN)

9/21/26, 2:00 PM

Invited

The Linac4 H⁻ ion source is a critical element of CERN’s operations, directly affecting both accelerator performance and its broad user base. As the sole injector particle source, its reliability and efficiency are essential to the stability of the entire proton accelerator chain and the physics programs it enables. This paper presents an overview of the system, drawing on six years of...

30. Ion Source Development for AMS at WHOI

Dr Mark Roberts (Woods Hole Oceanographic Institution)

9/21/26, 2:25 PM

Invited

Accelerator mass spectrometry (AMS) is a sensitive technique for counting single atoms. The technique was developed in nuclear physics laboratories in the late 1970s for $^{14}$C, and subsequently extended to other isotopes, including $^{10}$Be, $^{36}$Cl, and $^{129}$I. In general, the AMS method employs a positive high-voltage tandem accelerator to accelerate negative ions. Almost...

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)

9/21/26, 2:50 PM

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...
