Abstract

AbstractThe KSTAR (Korea Superconducting Tokamak Advanced Researc pursued to develop key technologies for superconducting tokamak operation and to contribute to a few research items for ITER relevant issues. As a result, the KSTAR achieved highly confined mode (H-mod in 2010 campaign and successfully demonstrated suppression of Edge Localized Mode (ELM) using n=1 Resonant Magnetic Perturbation (RMP) coils. The KSTAR is also initiating machine performance based on the designed machine parameters. The plasma current we achieved was 1 MA, and longest plasma pulse length has been extended to 10 s. In spite of limited heating power to 3.5 MW, several key actuators satisfactorily supported to implement a few scientific researches such as ELM control. On the basis of big progress in both the plasma performance and the experimental results, the KSTAR operation will explore key scientific and technical research issues under steady state operation condition in phase-2 operation.

9. Design and Operation of TE31,12High Power Gyrotron

Author

Kajiwara, K., Oda, Y., Takahashi, K., Kasugai, A., and Sakamoto, K.

Abstract

A high power gyrotron is designed and tested. The design is based on the TE31,81 MW gyrotron. The higher power design is realized by choosing TE31,12higher order oscillation mode. A basic test of the high power gyrotron is performed in JAEA test stand with short pulse and long pulse. In the short pulse experiments, 1020 kW output is confirmed with expected output beam pattern. In the long pulse experiments, it is successfully achieved stable 1 MW operation (1030 kW/2 s). The longest shot is 550 kW/~200 s. These results show successful design and fabrication of the TE31,12high power gyrotron.
