  2. 13. RF Upgrade Plans at DELTA
    Dr Peter Hartmann (DELTA, TU-Dortmund)
    16/11/2016, 09:50
    The 1.5 GeV storage ring Delta is currently equipped with a 40 kW klystron amplifier providing power to a single DORIS-type cavity. With the advent of a new wiggler in 2018 also the RF system will be upgraded. An overview of the upgrade and its current status is given.

  8. 7. Status and new developments of RF Systems of ALBA
    Ms Angela Salom (CELLS)
    16/11/2016, 14:35
    ALBA is a 3Gev 3rd generation synchrotron light source located in Barcelona and operating with users since May 2012. The RF system of the SR is composed of 12 IOTs, providing up to 80kW each. The power of every pair of IOTs is combined in a cavity combiner (CaCO) and transferred to each cavity (6 in overall) through a waveguide system. In this presentation we will cover RF operation...

    Dr Piotr Tracz (ELI-NP/IFIN-HH)
    16/11/2016, 16:20
    The Gamma Beam System – the future user facility – is being built in the framework of the Extreme Light Infrastructure–Nuclear Physics (ELI-NP) project in Bucharest/Magurele, Romania. This is an advanced source of gamma rays based on Compton back-scattering. By collision of a visible laser beam and a high brightness relativistic electron beam, an intense (~1011 γ/s), brilliant γ beam (<0.5%...

  13. 0. RF operation at the SLS and status of the SLS2 proposal
    Dr Lukas Stingelin (Paul Scherrer Institute)
    17/11/2016, 09:15
    In spring several hours of accumulated down time occurred because of klystron reflected power interlock. A dozen of power glitches caused the LINAC- and storage-ring RF systems to trip. In the LINAC pulse forming network cabinet, a high voltage cable was burnt due to arcing and triggered the fire extinguishing system. Mayor maintenance tasks of this year include and refurbishment of power...

    17/11/2016, 11:35
    The digital LLRF system for the SwissFEL was an internal development in the years 2012-2016 and is currently being installed and commissioned in the accelerator. It covers the different accelerating frequencies from S-band to C-band up to X-band and is built up in modular units. The tight SwissFEL requirements for stability demand a LLRF system which is capable to precisely measure amplitude...
