The unique closed divertor structure is its main characteristic. So far the obtained plasma current and toroidal field are Ip=410 kA and Br=2.7 T respectively, near the normal operation parameters of ASDEX. It is difficult to increase these parameters farther because of the engineering limit of the device.展开更多
