Dr V. Igochine Lectures on MHD

Dr. V. Igochine, a young researcher from Max-Planck Institute of Plasma Physics (IPP), visited ASIPP again from August 17 to September 1, 2012. In this stay, he gave series lectures about MHD study in Tokamak. His seminars were well-attended by both young PhD students and young researchers in ASIPP, some of them hailed his talks “instructive” and “enlightening” on their future experiments and study

In ASIPP meeting room, Dr. Igochine gave 7 lectures during his recent visit to ASIPP.  First lecture is about ‘Operation limits and MHD instabilities in modern tokamaks and in ITER’, in this talk Dr. Igochine discussed about the operation in modern tokamaks, and also introduced different kinds of MHD instabilities in tokamak, for instance, sawtooth, ELMS, NTMs and so on. In the lecture in that afternoon Dr.Igochine presented the recently study about the fast particles in modern tokamak.

In his lecture “Physics and control of sawteeth”, Dr Igochine discussed instabilities of tokamak experiments, and introduced the “Stochastic Reconnection Model” which could explain the fast sawtooth instability crash in ASDEX-U Tokamak. Furthermore, the different methods about sawtooth control also were presented in this lecture. After sawtooth physics lectures, Dr.Igochine discussed with ASIPP young researchers about ‘Recent progress in MHD simulations’.

In his last 3 three lectures. Dr. Igochine focused on the physics and control of NTM, ELMs and RWM. He identified the neoclassical tearing mode in experiments from the tearing modes. During the discussion, he proposed several kinds of methods on the control of the most dangerous NTM which may appear in EAST. And he also explained in detail the physics about ELMs and RWM.

After the lectures, many young PHD students actively discussed with Dr.Igochine. All of the lectures were appreciated by young researchers in ASIPP. (Xu Liqing reports)
