Abstract
Karlsruhe Institute of Technology (KIT) has started the development of gyrotrons for the first demonstration fusion power plant DEMO. A coaxial-cavity 238 GHz 2 MW gyrotron design is under investigation. After having obtained an initial cavity design, one focus of current studies is the associated triode-type magnetron injection gun (MIG). Constraints, design approaches and an initial gun design are presented. An outlook on further investigations is given.
