  1. 38. Pulse Current Analysis at BESSY II
    Anny Gora (Helmholtz-Zentrum Berlin HZB)
    24/04/2023, 14:30

    At BESSY II fast pulsed magnets are used for injection and extraction
    processes. Originally, pulse current measurement systems for all pulsed
    elements were set up in the framework of BESSY II top-up operation to
    show that the required level of voltage stability was achieved. Now it
    is essential for stable user operation at high average injection
    efficiencies of about 98 %. A model based...

  2. 29. Failure statistics and availability improvement of kicker systems at DESY
    Lukas Teichgraeber (DESY)
    24/04/2023, 15:00

    In the various circular and linear accelerators at DESY and European XFEL a total number of ca. 100 kicker systems is being operated.
    In recent years, a failure monitoring has been introduced for these systems to systematically study reasons for system failures and track down failure sources.
    In this talk we will discuss the failure statistics collected up to now and review the kicker...

  4. 27. Optimization of beam impedance mitigation measured for HV reliability in an SPS injection kicker
    Mike Barnes (CERN)
    24/04/2023, 17:00

    The SPS injection kicker magnets (MKP) were developed in the 1970’s, before beam induced power deposition in the ferrite yoke was considered an issue. These magnets are very lossy from a beam impedance perspective which limits SPS operation, e.g. with the higher intensity beams needed for HL-LHC. An upgraded design, with serigraphy applied to alumina U-chambers, has been developed to...

  5. 31. Design of a new Multipole Injection Kicker (MIK)
    Patrick Alexandre (Soleil)
    25/04/2023, 14:30

    Top-Up injection in the new SOLEIL II storage ring is planned to use an off-axis on-momentum betatron scheme. The final kick on the injected beam into the small dynamic aperture is given by a non linear kicker or MIK. To ensure the quality and transparency of the injection, the peak magnetic field generated by the MIK must be located at 3.5 mm from the stored beam axis while the zero-field...

  6. 30. New BESSY Booster Solid State Kicker Pulser Power Supplies
    Olaf Dressler (Helmholtz-Zentrum Berlin)
    25/04/2023, 15:00

    The BESSY booster kicker magnets have been powered with PFL type kicker pulsers since the BESSY II project was accomplished successfully. The kicker pulsers systems were realized with floating switch topologies applying CX 1154 thyratrons. After more than 25 years of operations the applied thyratron based kicker pulser units show wear and tear. The used pulser technology has obstacles for the...

  7. 39. Development of fast kicker prototype for SLS 2.0 advanced injection schemes
    Dr Martin Paraliev (Paul Scherrer Institute)
    25/04/2023, 16:00

    Swiss Light Source plans an upgrade to turn its existing Storage Ring (SR) into a modern diffraction limited light source (SLS 2.0). A 4-kicker bump scheme with new thick and thin septum will ensure the conventional injection in the smaller aperture of the new SR. To reduce further the perturbation of the stored beam during top-up, two new injection schemes are developed: “Fast” and...
