4. II II.1.4) Short description

The objective of this work package is to develop microwave vacuum windows for either circular or rectangular waveguide. There will be two general applications in which a analyse the ceramic is inserted into a waveguide or metallic wall: • Standard WR-## rectangular waveguide • Small circular or rectangular window with ceramic having a to metal bonding used in the microwave sources on joints that encounters excessively high index of refraction) thermal flux loads. The bonding should be compatible with ultra-high vacuum applications with leak rates kept below 10-9mbar/(l•s) The ceramic material work scope envisioned is to be determined based on for a supplier with the suppliers capability, materials index capabilities of refraction utilising 3D x-ray tomography, Scanning Electron Microscopes (SEM) and microwave transmission efficiency over an SEM with the range capability of 25 to 400GHz. The metallic material is preferred to be either Aluminium (allow 6061 or 6062) thermal and copper (CuCrZr). mechanical testing with simultaneous microstructural observations with both spatial and temporal resolution capabilities (hereafter referred to as specialist SEM). This work will also be used by the ITER organisation, as potential improvements to their future procurement of microwave sources for the proposed EC system upgrade.
