Title: A new technique for RF distribution

For independent phase and amplitude control, RF cavities are often driven by one power source per cavity. In many cases it would be advantageous in terms of cost to instead use one higher power source for many cavities. Vector modulators have been developed, which, when used with a single source provide for the independent phase and amplitude control which would have been otherwise lost. The key components of these vector modulators are a novel type of phase shifter — adjustable fast phase shifters with perpendicularly biased garnets. The vector modulators have been constructed and used with a single klystron in a 3.4 MeV test linac to successfully accelerate proton beam.
