The coaxial gyrotron with two beams

Summary form only given. The energy becomes one of the most crucial problems in the world. It is common recognition that Nuclear Fusion is considered the best approach to solve the energy problem. There two kinds of Nuclear Fusion: inertial confined fusion and magnetic confined fusion. The ITER (International Thermonuclear Experimental Reactor) might be a good promising potential expectation to solve this problem eventually. One of the biggest difficulties is the Plasma heating. To get the nuclear fusion occur, the high density plasma should be heated to over 100×1million K degree. The best approach is ECH. But it requires 1-2MW CW at 0.17 THz frequency. To do so, only Gyrotron is capable to generate such CW high power at such high frequency. However, after about 30 years efforts, 1-2 MW with only less than 1000 sec long pulse can be obtained. The Coaxial Gyrotron with two beams (CGTB) was invented in the year of 2005, theoretical study and computer simulation show that CGTB may solve this difficulties. Its characteristics and potential capability will be presented in this talk.
