  1. 11. Status of SRF Operation at NSRRC
    Dr Chaoen Wang (NSRRC)

    Status reports and projects
    Oral presentation

    Two modern light sources, the 1.5 GeV Taiwan Light Source (TLS) and the 3.0 GeV Taiwan Photon Source (TPS), are now routinely operated at NSRRC to service its user community. Both light sources are powered by the superconducting cavities. The SRF module of CESR-III design was selected for the TLS and has been routinely operated since the end of 2004. Two SRF modules of KEKB design were...

    The European Spallation Source (ESS) LINAC includes a specific section called “Spoke Section” with a row of accelerating structures designed for high power pulsed operation at 352.21 MHz. They consist in 26 superconducting spoke cavities, each one powered by a single RF power source, the RFPS. The spoke cavity RF power demand ranges between 260 kW to 330 kW depending on the proton beam...

    Fundamental power couplers
    Oral presentation

    The purpose of a radio-frequency system in a high-energy accelerator is to provide energy to the particle beam. A RF coupler is necessary to transfer the high power from a RF generator to the cavity. A coupler of coaxial type is a common choice. With high-power operation, it might suffer from multipacting, which is a resonance phenomenon due to re-emission of secondary electrons. Applying a...

    Oral presentation

    The CWRF workshop started 20 years ago in a pub-pizzeria in Chicago. An informal event grew into a renowned international workshop, hosting the world's leading experts on high power RF systems for particle accelerators.
    This talks looks back to the beginning and to the future.
