  1. 5. Development and Operation of the Homemade 500 MHz SC Cavity at IHEP
    Dr Jianping Dai (IHEP)
    6/26/18, 10:30 AM
    Status reports and projects
    Oral presentation

    A homemade KEKB-type 500 MHz superconducting cavity for BEPCII has been developed and operated with beam successfully at IHEP. The unloaded Q value of the cavity is about 2.5e9 at the routine operation voltage of 1.5 MV and the maximum measured voltage is 2.17 MV with a Q0 of 5.8e8. A brief introduction on the cavity’s fabrication, vertical test, horizontal test and beam operation will be presented.

  2. 32. Improvements to RHIC Landau damping cavity for high intense ion beams, and issues with increasing RF pulse width on drift tube linac cavity.

    Status reports and projects
    Oral presentation

    Beam loading improvements were performed to the RHIC landau damping cavity, with the addition of an external loading network. The improvement is required to achieve a beam intensity of 3.0x10^9 Au Ions/bunch.
    A status update of the 200MeV drift tube linac pulse width upgrade will be discussed. The increased RF pulse width from .6mS to 1.1mS results in drift tube spring ring failure.

  3. 7. Overview of the high-power CW RF systems of the WEST tokamak and some other new developments
    Dr Walid Helou (CEA, IRFM, F-13108 St-Paul-Lez-Durance, France)

    Status reports and projects
    Oral presentation

    In a steady-state nuclear fusion reactor of the tokamak type, energetic neutral beam injectors and high-power CW RF systems should be employed. These systems are needed to heat the plasma up to the required temperatures of 10-20 keV and to drive a non-inductive plasma-current which is required for the plasma confinement. This paper overviews at first the aforementioned systems and emphasizes...
