Accelerator components made of technical ceramics

Vacuum chambers made of Oxide Ceramics are used in accelerator units. In contrast to metallic parts, ceramic components avoid shielding of the rapidly changing external magnetic fields. Ceramic material is not heated by eddy currents. The additional coating on the inner surfaces of the ceramic chambers, e.g. Ti or TiN, ensures the reliable discharge of image current and prevents the emission of secondary electrons. Technical Ceramics also displays outstanding properties of electrical insulation. The dielectric strength of the material lies at >30 kV/mm. F99.7 Oxide Ceramics are used in a number of renowned German institutes. These include the German Electron-Synchrotron (DESY) based in Hamburg and Zeuthen, the Jülich Research Centre (FZJ), the Helmholtz Centre for Heavy-Ion Research (GSI) in Darmstadt and the Karlsruhe Institute of Technology (KIT). Also at international level, accelerator technology relies on Oxide Ceramics: the Large Hadron Collider (LHC) at CERN, the European Organisation for Nuclear Research in Switzerland and Cornell University, Ithaca, USA.
