UHV Capabilities Overview
Ultra-High Vacuum Compatible Waveguide RF Devices
Microwave Techniques produces an array of Ultra High Vacuum (UHV) compatible waveguide RF devices. These products are custom-manufactured to provide high electrical performance in the UHV and vacuum environment down to 1 x 10-11 Torr. All components use vacuum rated materials such as OFHC copper, non-magnetic stainless steel, and ceramics such as quartz, alumina, and sapphire. Our manufacturing processes involve advanced welding and vacuum brazing techniques. All ultra-high vacuum sweep bends are cleaned, assembled, tested and stored in our clean room.
