  1. 82. An Expanded Survey of H-/D- Injectors at National Laboratories: Ion sources, LEBTs and RFQs
    Robert Welton (ORNL-SNS)
    9/24/26, 1:30 PM
    Invited

    Modern low-energy H-/D- injectors are used extensively in many large, accelerator-based, user facilities operating worldwide. Beams of these ions are used to fill circular accelerators and storage rings, to enable efficient extraction from cyclotrons and to double proton energy output from a tandem accelerator. The injector consists of an ion source, a Low Energy Beam Transport (LEBT)...

  2. 96. Modeling of Beam Focusing with Radio Frequency Electric Field Perturbations
    Tsuyoshi Yasui (Nagoya University,Japan)

    Contributed Oral

    A critical issue in the development of radio frequency (RF) negative ion sources for ITER neutral beam injection (NBI) is the large beam divergence angle. One of the potential causes is the deformation of the beam extraction interface (meniscus) induced by the RF electric field. Previous work showed that the applied RF electric field near the meniscus triggered both oscillations and an...

  3. 78. The DC voltage holding experiments in vacuum under cesium deposition condition
    Dr Bo Liu (Institute of Plasma Physics, Hefei Institutes of Physical Science, Chinese Academy of Sciences, Hefei 230031, China)

    Abstract: Cesium injection is an effective and relatively mature method to improve the negative ion yield of negative ion sources. Cesium deposition on the component surface of negative ion based neutral beam injector (NNBI) accelerators is one of the key factors affecting insulation performance. At present, the correlation between cesium deposition amount and inter-electrode insulation level...

  4. 160. Realta Fusion's Roadmap & Diagnostic Development
    Anthony Cooper (Realta Fusion)
    9/24/26, 2:35 PM
    Contributed Oral

    Realta Fusion is developing a tandem mirror machine, Hammir-DD, to achieve fusion-relevant temperatures using a high-powered negative-ion-based neutral beam injector (NNBI). We will experimentally verify this technology on a full-scale, single source test bed which is targeting a 200 keV beam with approximately 1 MW of neutral power for up to one second of operation.
    In parallel, Realta is...
