  1. 24. RF distribution systems at ESS
    Mr Walther Borg (European Spallation Source ERIC)
    13/09/2022, 09:45
    Passive devices and transmission systems
    Oral presentation 20' + 5'

    ESS is installing and testing the RF distribution systems including waveguide and coaxial components, circulators, RF loads for up to 155 high power RF systems; > 5000 RFDS components. This talk will present the early quality issues, waveguide tuning and how they were resolved. RFDS components are often considered trivial however, the initial high power operation revealed a number of serious...

  2. 23. ESS arc detector systems, development and experience
    Mr Tomas Olsson (European Spallation Source ERIC)
    13/09/2022, 10:10
    New technology, new ideas, R&D, other technically interesting contributions
    Oral presentation 20' + 5'

    ESS is deploying a number of different arc detector systems to protect the RF and distribution systems. ESS are currently installing and testing three different systems. The initial installation and early batches were based on commercial systems but we will also present the test results, motivation and performance parameters of the more recent arc detectors constructed at ESS. Early high power...

    Oral presentation 25' + 5'

    In a steady-state nuclear fusion reactor of the tokamak type, high-power CW RF systems are envisaged, among other systems, 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 the so-called Ion Cyclotron Range of Frequencies (ICRF) system of the International Thermonuclear...
