Abstract. Major disruption is a serious problem for tokamak operation. The major disruption can be caused by several reasons, for example, the low-q discharge, the MHD instability and mode locking, the vertical displacement events (VDEs) and the high density operations. When the major disruption occurs, it can not only generate great heat loads on the first wall and divertor plates, but also leads to the large electromagnetic force because of the halo current. Therefore, how to avoid the disruption is an important issue on tokamak operation. To control and mitigate it, the mechanism and the characters of disruption have to be well known. A lot of experimental and theoretical studies of the major disruptions have been presented.

Abstract.Soft x-ray emission from tokamak plasma is dependent on various plasma parameters, such as density and temperature, and one can thus infer information about them by observing this radiation. For multi-Channel diagnostics, computed tomography is necessary to reconstruct the 2-D spatial distribution of the emission intensity g(r, ¦È ) in a plasma. It is therefore that soft x-ray tomography becomes an important tool to study various phenomena in fusion plasma, such as sawtoothing, m=1 precursor oscillation, snake, m¡Ý2 instabilities, disruption, as well as plasma

position, impurity radiation, etc. In plasma physics, several researches[1-4] have attempted to use the principles of tomography to gain information about the soft x-ray emissivity. Now, there are various methods to gain the tomographic results, such as Analytic tomographic algorithm; Hybrid tomographic algorithm[5]; Maximum entropy techniques[1], etc. Analytic tomographic algorithm is widly used in fusion plasma research and it is the basic tomographic method used in HL-2A.

In this paper, a systerm which obtains the multichannel soft x-ray data needed to perform tomographic reconstructions of HL-2A plasma is described. In Sec. 3, a brief description of the reconstruction algorithm is presented. And some analysis results including large sawtooth activity and snake-like perturbation during molecular beam injection are shown in Sec. 4.

The HL-2A tokamak and the recent experimental results will be presented in this paper. Up to now, the following operation parameters have been achieved in the device: Ip = 320 kA, Bt = 2.2 T and discharge duration T= 1580 ms. With the feedback control of the plasma current and position, the tokamak has been operated at single null (SN) divertor configuration. The impurity radiation and the recycling decrease remarkably during the divertor configuration. Some experimental results, such as siliconization wall conditioning, modulated molecular beam injection (MBI) and major disruption of the density limit study have also been carried out. The HL-2A tokamak will be operated at Ip = 450 kA, BT = 2.5 T, plasma duration t > 2 s in 2005. More experiments will be carried out with 1MW LHCD and 1MW ECRH system in next year.
