| Research Abstract |
For start-up of future superconducting tokamaks such as ITER, non inductive formation of initial closed flux surfaces by electron cyclotron heating is quite beneficial. While this was possible in low aspect ratio devices, there were few experiments at a conventional aspect ratio of R/a=3. In the Low Aspect ratioTorus Experiment device a series of experiments has been done by using a movable limiter to adjust the aspect ratio of plasmas up to R/a=3. The results show that the formation of closed flux surfaces is still possible up to R/a=3 while higher decay indexes of vertical field are required as the aspect ratio increases.
