A 1.5 MW, 140 GHz, TE{sub 28,16}-coaxial gyrotron with an inverse MIG is under development. Preliminary rf-tests using an axial rf output and a simple cavity with a constant diameter and non-corrugated inner rod gave an rf output power of 1 MW with an efficiency of 23% at 140 GHz (TE{sub 28,16}) and 1.3 MW with an efficiency of 29% at 133 GHz (TE{sup 27,15}). No indications of beam instabilities in the beam tunnel between the IMIG gun and the cavity have been observed. Experiments with an improved cavity and the design of the tube with a radial dual Gaussian beam output and a depressed collector are underway.
