Abstract

The design of a 1 MW, 280 GHz gyrotron suitable for ECR heating is complete and under construction at MIT. A highly overmoded cylindrical cavity with linear tapers at each end will operate in the whispering gallery mode; TE_42,7,1. The magnetron injection gun (MIG) was optimized to produce a 90 kV, 50 A annular electron beam with an α = υ/υ|| =1.6 and a perpendicular velocity spread of approximately 5 %. The MIG and a 12 Tesla superconducting magnet with a 5 inch warm bore are presently under construction. Initial operation is planned for early next year.
