Abstract

New vacuum feedthrough has been recently designed for the ASDEX Upgrade ICRF system. Vacuum feedthroughs in general can limit the voltage standoff of high power RF systems. ICRF vacuum feedthroughs are no exception, they require careful design, as well as qualifications and testing prior to installation to the antenna. The paper shows the design of a new full wavelength resonator test facility for the new ASDEX Upgrade ICRF antenna vacuum feedthroughs. The new test facility is an extension to ISHTAR (Ion-cyclotron System Hardware Test Arrangement) and is designed to have two configurations: the first one with two new 9-inch windows with improved surrounding structures (corona rings or arc traps); the second one with a 6-inch window with old-existing surrounding structures and one new 9-inch window. A set of high power tests (∼400 kW, ≤10 s) are planned using ASDEX Upgrade ICRF generator 5 in order to achieve the same voltage stand-off as it is during the ICRF system operation on ASDEX Upgrade. Different ceramics are characterized and considered for ASDEX Upgrade RF windows.

期刊介绍： The journal accepts papers about experiments (both plasma and technology), theory, models, methods, and designs in areas relating to technology, engineering, and applied science aspects of magnetic and inertial fusion energy. Specific areas of interest include: MFE and IFE design studies for experiments and reactors; fusion nuclear technologies and materials, including blankets and shields; analysis of reactor plasmas; plasma heating, fuelling, and vacuum systems; drivers, targets, and special technologies for IFE, controls and diagnostics; fuel cycle analysis and tritium reprocessing and handling; operations and remote maintenance of reactors; safety, decommissioning, and waste management; economic and environmental analysis of components and systems.
