Abstract
To achieve high mode purity, RF beam alignment method of mirrors and design of phase correcting mirrors are discussed. The phase correcting mirror was designed using measured gyrotron output beam profile. The designed couple efficiency into LP01 mode was 98%. The tolerance of alignment between RF beam and mirrors was also discussed.
