| Research Abstract |
The purpose of this study is to obtain the basic data for the ELM control with ELM heat flux simulation by the ECH power modulation on the GAMMA 10 mirror device. We have succeeded in getting arbitrary intermittent heat flux with the modification of the ECH system. The more than 10MW.m2 heat flux density which is 10 times higher than the base heat flux has been produced by the ECH and the intermittent heat flux have been characterized, measuring the radial distribution of heat flux, effective temperature and so forth. These indicate the active control of the heath flux parameters is possible by ECH modulation. It is also obtained the preliminary data of the tungsten target interaction with the intermittent heat flux.
