Abstract :
Some gyrotrons use an internal launcher and a series of mirrors to shape the cavity mode into a Gaussian beam at the output. We discuss the design and cold testing of a pair of iteratively designed cylinder-based beam-shaping mirrors to transform the launcher output into a Gaussian beam at the output. One additional weakly curved planar-based mirror directs the beam out of the gyrotron window.
