Abstract

KfK is continuing the development of 140 GHz high power gyrotrons for electron cyclotronwave (ECW) applications. Experiments with a TE10,4 mode gyrotron have been performed usingan axial rf output coupling. The achieved maximum output power of this version amounted to0.7 MW in the design mode with a mode purity of about 99 % and an electronic efficiency of26 %. Since these experiments have been performed using the superconducting magnet systemdesigned for the previous TE0,3 mode tube the pulse length was limited to 5 ms. With a moreappropriate magnet system with increased bore hole diameter which allows the use of a built-inquasioptical converter a pulse length of up to 300 ms with 0.5 MW rf power is expected.In the following we will present some experimental results with respect to frequency step- tuning of the TE10,4 mode gyrotron and describe the radial output coupling system.
