  1. 16. SRF performance on the Compact ERL at KEK
    Hiroshi Sakai (KEK)
    10/4/22, 1:30 PM
    SRF
    Presentation

    A superconducting Compact Energy Recovery Linac (cERL) was constructed in 2013 at KEK to demonstrate energy recovery concept with low emittance, high-current CW beams of more than 10 mA for future multi-GeV ERL. cERL consists of 500 kV DC photocathode gun, the injector cavities, the main linac cavity, which made energy recovery, recirculation loop and the beam dump.Under long-term beam...

  3. 14. SRF photo-injector and Booster modules at bERLinPro: Assembly and commissioning status
    Axel Neumann (Helmholtz Zentrum Berlin)
    10/4/22, 2:10 PM
    SRF
    Presentation

    The energy recovery linac (ERL) at Helmholtz-Zentrum Berlin (HZB) is in the final stage of assembly and follow-up commissioning of the injector beam line. This injector consists of a 1.4\lamba/2 cell SRF photo-injector and a three two cell Booster cryomodule, the latter based on a modified design of the Cornell injector cavity shape. The injector was designed for a final beam current of 100...

  5. 24. Design of the 9-cell superconducting cavity for EUV light source accelerator
    Taro Konomi (FRIB)
    10/4/22, 2:50 PM
    SRF
    Presentation

    KEK has been designing the 10 mA class ERL-EUV light source accelerator. The main linac uses 9-cell superconducting cavities with beamline HOM damper. The target accelerating gradient is 12.5 MV/m. The 9-cell cavity is designed from experience of the KEK compact ERL (cERL) main linac. The cERL main linac was designed to suppress the HOM-BBU with beam current of 100mA by enlarging the iris...

  6. 25. Horizontal test of Superconducting RF gun #2 at KEK
    Taro Konomi (FRIB)
    10/5/22, 2:45 PM
    SRF
    Presentation

    Superconducting radio-frequency (SRF) electron guns are attractive for delivery of beams at a high bunch repetition rate with a high accelerating field. KEK has been developing the SRF gun to demonstrate basic performance. The SRF gun consists of 1.3 GHz and 1.5 cell SRF gun cavity and K2CsSb photocathode coated on 2K cathode plug. In the vertical test, the surface peak electric field and the...

  10. 72. SRF Operations, microphonic control at CBETA
    Nilanjan Banerjee (The University of Chicago)
    10/6/22, 8:50 AM
    SRF
    Presentation

    The Cornell BNL ERL Test Accelerator (CBETA) is the first machine which achieved multi-pass energy recovery employing superconducting cavities. While SRF cavities operated with a narrow bandwidth reduce the overall power consumption of the main linac, maintaining stable field required for energy-recovery in the presence of microphonics detuning becomes a challenging task. We discuss the...

  11. 4. HOM-Damping Studies in a Multi-Cell Elliptical Superconducting RF Cavity for the Multi-Turn Energy Recovery Linac PERLE
    Mr Carmelo Barbagallo (IJCLab - Université Paris-Saclay)
    10/6/22, 9:10 AM
    SRF
    Presentation

    Higher order modes (HOMs) damping is a crucial issue for the next generation of high-current accelerators. Beam-induced HOMs can store sufficient energy in the superconducting RF (SRF) cavities giving rise to beam instabilities and increasing the heat load at cryogenic temperature. To limit these effects, the use of HOM couplers on the cutoff tubes of SRF cavities becomes crucial to absorb...
