Area of Science:

  • Particle Accelerators
  • Power Electronics
  • Synchrotron Radiation

Background:

  • Traditional klystron power supplies in storage rings often rely on crowbar circuits.
  • Crowbar circuits can be expensive, unstable, and introduce voltage ripple.
  • The New SUBARU storage ring requires stable power with minimal voltage ripple, especially in quasi-isochronous operation.

Purpose of the Study:

  • To introduce a novel crowbarless power supply system for the New SUBARU storage ring.
  • To demonstrate the effectiveness of a high-power switching inverter in replacing conventional crowbar circuits.
  • To achieve significantly reduced low-frequency voltage ripple for enhanced storage ring performance.

Main Methods:

  • Installation of a new high-power switching inverter unit.

  • Integration of the inverter with the klystron power supply system.
  • Testing and validation of the power supply's stability and voltage ripple characteristics.

    • Main Results:

    • Successful elimination of the need for expensive and unstable crowbar circuits.
    • Realization of very small voltage ripple in the low-frequency region.
    • Demonstrated suitability for quasi-isochronous storage ring applications.

    Conclusions:

    • The crowbarless power supply with a switching inverter offers a more stable and cost-effective solution.
    • The reduced voltage ripple is a key advantage for sensitive storage ring operations like New SUBARU.
    • This advancement contributes to improved reliability and performance in particle accelerator power systems.
