Hα Emission Imaging during Supersonic Molecular Beam Injection by CCD Photograph

There are several fuelling methods for tokamak plasma： pellet injection （PI）, gas puffing （GP）, neutral beam injection （NBI） and supersonic molecular beam injection （SMBI） .SMBI has been created in the Southwestern Institute of Physics, China.     

Tokamak Experiment and Tokamak Engineering——Development of the Plasma Diagnostics on HL-2A Tokamak

The main mission the HL-2A tokamak is of the experiments on to explore the divertor physics and to investigate the plasma confinement, transport and instabilities with high power auxiliary heating and advanced fuelling, it is necessary to develop more new diagnostics and increase the spatial and temporal resolutions of the measurements for exist system. Up to now, about 30 diagnostic systems have been moved from HL-1M to HL-2A tokamak. Other 10 diagnostic systems are being designed and installed on the device. In developed in last 2 years, will be presented.     

Calculation of the Safety Factor of the Ohmic HL-2A Single Null Divertor Discharge

The safety most important factor profile is one of the the plasma discharge. For limiter configuration, people usually use the following cylindrical approximation formula to calculate it q（r）=5r^2BT/RIp where r is the minor radius of the plasma toms, R is the major radius （in m） , BT is the toroidal magnetic field （in T）, Ip is the total toroidal current（in MA）.     

工艺参数对铀表面铝镀层热应力分布影响

为了防止铀的腐蚀，采用在铀表面磁控溅射镀铝，但使用中发现铝镀层内产生了较大的应力，影响镀层结合强度及使用性能。通常认为，薄膜内的应力有热应力和生长应力两种。文中通过改变沉积温度、镀层厚度以及镀层力学性能分数，研究它们对镀层热应力分布的影响，从而为改善铀表面铝镀层内热应力分布提供理论依据。     

Geodesic Acoustic Mode in Toroidally Axisymmetric Plasmas with Non-Circular Cross Sections

The geodesic acoustic mode （GAM）, first predicted by Winsor, Johnson and Dawson in an attempt to explain some experimentally observed low frequency oscillations in stellarators, is a special electrostatic fluid mode with low mode number and coupled with the so-called geodesic curvature of a toroidally confined plasma. The recent on this mode are due to the close relevance of the stabi- lization of drift turbulence by both the zonal flow and the GAM. Previously, the GAM was illustrated in very simple geometries,     

Formation Mechanism and Orderly Structures of an Iron Film System Deposited on Silicone Oil Surfaces

A new iron film system,deposited on silicone oil surfaces by vapour phase deposition method,has been fabricated and its formation mechanism as well as orderly structures has been studied,It is found that the formation mechanism of the films obeys a two-stage growth model,which is similar to that to the other metallic films on liquid substrates,Large and orderly structures are observed in the continuous iron films.The experiments show that the orderly spatial structures result from the local material gathering in these nearly free sustained films.
