  1. 24. Cavity combiners for high power solid state RF amplifiers
    Mr Michel LANGLOIS (ESRF)
    06/05/2010, 13:30
    Cavity combiners have been used before: at ALBA, for instance, 2 IOTs add their output power in such a device to drive one storage ring accelerating cavity. Their main advantages lie in the minor footprint when compared to hybrid couplers and their capability to accept a large number of feeders. This makes them ideally suited for high power transistor amplifiers, where many pallets have to be...

  2. 13. Status of High Power Solid State Amplifiers for the ESRF
    Mr Jean-Maurice MERCIER (ESRF)
    06/05/2010, 14:00
    As presented in detail at the CWRF’2008 workshop, the ESRF RF system will undergo a major upgrade, klystrons being replaced with high power solid state amplifiers (SSA) and existing five-cell cavities of the storage ring with strongly HOM damped single cell cavities. The company ELTA, who has a technology transfer contract with SOLEIL, was selected to produce the first batch of seven 150 kW...

  3. 18. Hot S22 Measurement of LHC Circulators
    Dr Nikolai Schwerg (CERN)
    06/05/2010, 14:30
    The LHC accelerating RF system merely consists of a 300 kW klystron, a 3-port circulator, a superconducting cavity and an RF load. The resonance of the superconducting structure is strongly influenced by the external RF system. The loaded Q, i.e. the external quality factor of the cavity, therefore also depends on the reflection of the circulator. The circulators are equipped with a...

  4. 15. WAVEGUIDE DISTRIBUTION SYSTEM FOR FLASH
    Dr Valery Katalev (DESY)
    06/05/2010, 15:30
    The linear accelerator for the Free Electron Laser in Hamburg (FLASH) contains fifty six superconducting cavities grouped into seven cryogenic modules and one normal conducting RF gun. The five RF stations using 5MW single beam and a 10MW multibeam klystrons supply the cryogenic modules and the gun through the distribution system based on WR650 waveguides. Since FLASH is based on the Tesla...
