  1. 68. Bunch compression methodologies in the ISIS Rapid-Cycling Synchrotron (WECDB01)
    Billy Kyle (ISIS Neutron and Muon Source)

    Contributed Oral Presentation

    The ISIS rapid-cycling synchrotron accelerates a high-intensity
    beam of protons from 70 MeV to 800 MeV at 50 Hz,
    facilitated by ferrite-loaded RF cavities at harmonics ℎ = 2
    and ℎ = 4. The extracted proton beam is delivered along
    separate transfer lines to two tungsten spallation neutron targets,
    TS1 and TS2, at rates of 40 Hz and 10 Hz respectively.
    An intermediate carbon target on the...

  2. 62. Simulations of beam-coupling impedance to guide model-based mitigations in Hadron Rings (WECDB02)

    Contributed Oral Presentation

    Beam coupling impedance is a fundamental performance limitation in high-intensity hadron rings, affecting both beam stability and the thermal load on accelerator components. As beam intensity increases, impedance-driven collective effects—such as transverse mode coupling and longitudinal coupled-bunch instabilities—become more pronounced, while beam-induced power losses can cause local...

  3. 14. Optimization of beam performance by correction of impedance driven tune shifts at the CERN SPS (WECDB03)

    WGA:Beam Dynamics in Rings
    Contributed Oral Presentation

    High-intensity multi-bunch beams in the CERN Super Proton Synchrotron (SPS) experience significant coherent and incoherent tune shifts due to the transverse beam coupling impedance. Studies with LHC-type beams have been performed to optimize the working point along the extended SPS injection plateau to enhance beam performance and brightness. The initial tune correction approach focused on...
