Study of Ka-Band High-Power Transmission Lines

Analysis is presented of several high‐power transmission lines designed and built for use with a future normal‐conducting high‐energy collider. The transmission lines contain a number of components such as mode converters, bends, windows, combiners‐splitters, pumping ports, and compensators. Designs of these components take into account efficiency, reliability, and compactness. Low‐power tests of key components, as well as recent high‐power tests carried out in CERN, are described
