实习题目:
适用于托卡马克高约束模放电的高频扫描探针的研发
Development of a High Frequency Scanning Probe for H-mode Discharge in a Tokamak
实习内容:
静电探针是一种直接与等离子体接触的主动诊断,结构相对简单,具有很高的空间分辨和时间分辨。可以测量等离子体边缘的许多重要基本参数。托卡马克在高约束模放电模式下,边缘区等离子体温度和密度较高,因此对该区域等离子体参数的测量提出了挑战。高频扫描探针对等离子体干扰小、测量的信息量丰富,因而成为H模边缘物理研究的重要工具。基于HL-2A托卡马克装置的边缘区等离子体参数,本次实习将设计一套可应于HL-2A的高频扫描探针系统。
Electrostatic probe is a one of active diagnosis which is directly in contact with plasma. It has simple structure, low cost and high spatial and temporal resolution. Many important basic parameters of plasma edges can be measured. Measuring plasma parameters in H-mode in tokamaks in the high temperature and density edge region poses a significant challenge. To study the edge physics, high-frequency scanning probes are important tools due to their minimal disturbance to the plasma and ability to provide rich measurement information. This activity focuses on designing a set of high-frequency scanning probe systems that can be applied to the HL-2A tokamak device, specifically for measuring plasma parameters in the edge region.

实习题目:
数字化托克马克的研发
The Development of Digitalized Tokamak
实习内容:
托克马克等离子体放电实验,每次需要消耗较多的资源,且一旦实验条件变化,则需要花费较多的准备时间。为快速且低成本的验证一些等离子体理论分析,或者提前预测真实放电实验的结果能否有可能达到预期,需要实现不同装置仿真系统的互通串联提高计算准确性。因此,数字化托克马克的仿真平台逐渐成为业界研发重点,该系统平台不仅能够提升等离子体理论工作的效率,而且也能更方便获取与处理实验数据。本次实习活动将基于HL-2M托卡马克装置的数字化托克马克平台,设计一种特定场景下可用于等离子体实验物理过程仿真的子系统。
Plasma discharge in Tokamak requires a significant amount of resources for each experiment, and once the condition of experiment changes, we need spend several days for the preparation. In order to quickly and low-cost validate some plasma theoretical analyses, or predict in advance whether the results of real discharge experiments may meet expectations, it is necessary to realize the inter-working of different device simulation systems to improve the calculation accuracy. Therefore, the digital Tokamak simulation platform has gradually become a focus of industry research and development. This system platform not only improves the efficiency of plasma theoretical work, but also provides more convenient access and processing of experimental data. Based on the digital Tokamak platform of the HL-2M tokamak device, this internship will design a sub-system that can be used to simulate the physical process of plasma experiments in a specific scenario.

【实习课题 3】
实习题目:
面向聚变堆的先进钨铜偏滤器模块高热负荷实验研究
实习内容:
钨基材料被认为是未来聚变堆中最有希望的面向等离子体材料,耐高热负荷能力是其最核心性能之一。相比纯钨,先进钨基材料具有更优异的力学性能和更高的再结晶温度;但是,先进钨基材料的耐高热负荷性能数据还非常缺乏,其能否适应未来聚变堆严苛的高热负荷运行要求,还需更深入的研究。一方面,需要对先进钨基材料在瞬态高热负荷条件下的耐热冲击性能进行研究;另外一方面,需要将先进钨基材料制备成为模块/部件,对先进钨基材料在稳态高热负荷条件下的行为进行研究;此外还需通过瞬态和稳态高热负荷实验协同评估先进钨基材料的耐高热负荷能力。本实习的主要任务利用60kW电子束高热负荷实验装置(EMS-60)对先进钨铜焊接水冷模块在稳态高热负荷条件下的行为进行研究,并对高热负荷实验后模块的微观组织进行分析。
