Abstract
Coaxial-cavity gyrotrons are microwave sources that can extend the possible power levels of hollow cavity gyrotrons significantly and make them attractive for future fusion experiments and power plants. KIT already demonstrated operation of a modular short-pulse 170 GHz coaxial-cavity gyrotron with an output power of 2.2 MW, operating in the TE34,19mode. Today’s focus of KIT is the verification of this technology at longer pulses, which will prove the long-pulse capabilities also. At the moment, the current KIT prototype has been extended with cooling capabilities for all critical, highly loaded components of the tube and two new, different electron guns are available for operation. This paper will give an overview about the recent status and the future prospects connected to the coaxial-cavity gyrotron development at KIT, including both experimental and theoretical activities.
Highlights
At KIT, the activities in gyrotron research and development shall lead to a gyrotron design that will fulfil the increasing requirements for future nuclear fusion experiments and power plants, like DEMO [1], the fusion demonstration power plant that will follow ITER
KIT is pushing forward the coaxial-cavity gyrotron development by building up a modular longer-pulse 170 GHz, 2 MW pre-prototype targeting at pulse lengths of up to 1 s
The Inverse Magnetron Injection Gun (IMIG) was manufactured at KIT with an expected high electron beam quality
Summary
At KIT, the activities in gyrotron research and development shall lead to a gyrotron design that will fulfil the increasing requirements for future nuclear fusion experiments and power plants, like DEMO [1], the fusion demonstration power plant that will follow ITER. Intense theoretical design activities to support the manufacturing have been performed and are still ongoing to assist during the experimental activities This includes the design and optimization of different kinds of Magnetron Injection Guns (MIGs) [11], the simulation of the gyrotron interaction [12,13] and quasi-optical output launcher [14,15] (focusing on a future dual frequency operation at 170 GHz / 204 GHz).
