Measurements of Boundary Plasma in Synergy Discharges of IBW and LHCD on the HT-7 Tokamak

By applying ion Bernstein wave (IBW) heating into the lower hybrid current drive (LHCD) plasma, improved confinements have been obtained in the HT-7 tokamak. The central electron temperature was doubled and the storage energy was increased significantly. The core electron density and temperature were broadened and ther profiles near the edge were steepened. A transport barrier has been formed in the vicinity of the limlter radial location. An enhanced shear in poloidal phase velocity was found in the same region with reduction of the fluctuation levels and the coherences between fluctuations. The results suggest that the improved confinement in the IBW and LHCD plasma is at least partially due to the modification of shear in poloidal velocity and then the suppression of fluctuations and fluctuation induced fluxes via de-correlation effect.     

Application of CPLD in CSR Control System

CPLD is the complex programmable logic device. The logic function of CPLD can be changed by different; program. The applications of CPLD have not only simplified the circuit‘s design and reduced its costs, but also enhanced the reliability and secrecy of the system. Here we introduce an example of the CPLD‘s implementation in the CSR control system.

AFTEX—3000F型ECR溅射装置

电子回旋共振(ECR)等离子体法广泛用于SiO_2、Si_3N_4膜等的低温CVD技术,以及MOS器件的微细栅极刻蚀技术。在ECR等离子体法中,由于低气压下生成高离子化的等离子体,故以低能量、大的离子电流照射而能持续进行表面反应,然而以往的技术无法实现高质量的薄膜工艺。由于用固体靶溅射,靶材供给容易,进而把上述技术作为基础,开发了ECR溅射技术。
