The Experiment of Modulated Toroidal Current on HT-7 and HT-6M Tokamak

The Experiments of Modulated Toroidal Current were done on the HT-6M tokamak and HT-7 superconducting tokamak. The toroidal current was modulated by programming the Ohmic heating field. Modulation of the plasma current has been used successfully to suppress MHD activity in discharges near the density limit where large MHD m = 2 tearing modes were suppressed by sufficiently large plasma current oscillations. The improved Ohmic confinement phase was observed during modulating toroidal current (MTC) on the Hefei Tokamak-6M (HT-6M) and Hefei superconducting Tokamak-7 (HT-7). A toroidal frequency-modulated current, induced by a modulated loop voltage, was added on the plasma equilibrium current. The ratio of A.C. amplitude of plasma current to the main plasma current △Ip/Ip is about 12% ～ 30%. The different formats of the frequency-modulated toroidal current were compared.

H_α/ D_α Measurements Based on Photo Diode Array in the HT-7 Tokamak

1. IntroductionThe measurement of H./D. emission, which canafford much information of the plasma, is one of the-,primary diagnostics in tokamak experiments. If theintensity Of H./D. emission along different chords ina poloidal plane are measured, with the ABEL inver-sion, one can get the H./D. emissivity, thus the spatial distribution of neutral H/D and its penetrationor ionization length. With the absolute brightness ofH./D. emission and assuming some symmetries inspatial distribution, …     

新工科背景下将人生感悟融入化学课堂教学的探析

现代高等教育更加注重学生综合素质的培养,新工科概念的提出愈加强调学生创造力和人文情怀的提升。人生与化学虽属不同的体系,却在内涵上融会贯通,在哲理上相似相容。笔者在讲授化学课程时融入人生感悟,在传授知识的同时强化育人,这对于有效实现“课程思政”、在课堂教学中立德树人、提升学生对化学知识的理解、活跃课堂气氛及达成教学目标等方面均具有明显的效果。

Methods of Power Balance Analysis and Estimation of Current Density Profile for LHCD and IBW Discharges in HT-7 Tokamak

In this paper a simple code has been developed to analyze power balance and qualitatively evaluate current profiles for discharges with lower hybrid current drive （LHCD） and ion Bernstein wave （IBW） heating in the HT-7 tokamak. Electron and ion thermal diffusivity, profiles of the bootstrap current density and total plasma current density can be estimated by this code using the experimental data. This code offers an easy and reasonable means to understand plasma transport in HT-7.
