Abstract

The high magnetic field compact high-temperature superconducting tokamaks are characterized by high energy density, macroscopic instabilities, and high threshold values, which are beneficial to the operation of the device with high parameters, however, this also directly leads to a sharp increase in the heat loads of the divertors. Therefore, in this paper, with reference to the design parameters of SPARC, the TSC is used to simulate the double-null divertor sweeping configuration discharge process of a high magnetic field compact tokamak device (HFCT), and the heat flux distribution on the surface of the target at the time of divertor outer long-leg sweeping in the discharge flat-top stage is obtained, with the peak value of 23.2 MW/m2; both water-cooled monoblock and all-tungsten divertor configurations calculated using ANSYS, which concluded that the tungsten armor thickness d in the all-tungsten divertor configuration should not be greater than 2.5 mm to withstand a peak heat flux of 23.2 MW/m2; on the basis of this configuration, the temperature field of the divertor target is calculated for different sweeping fields and the feasibility of the all-tungsten divertor target model is analyzed. This study can be used as a reference for the design of divertor target in future HFCT.

高磁场紧凑型托卡马克导流靶热负荷缓解研究
高磁场紧凑型高温超导托卡马克具有高能量密度、宏观不稳定性和高阈值等特点,有利于高参数器件的运行,但这也直接导致了导流器热负荷的急剧增加。因此,本文参照SPARC的设计参数,利用TSC模拟了高磁场紧凑托卡马克装置(HFCT)双零导流器扫流配置的放电过程,得到了放电平顶级导流器外长腿扫流时靶体表面热流密度分布,峰值为23.2 MW/m2;采用ANSYS对水冷单块和全钨导流器构型进行了计算,得出全钨导流器构型的钨护甲厚度d不应大于2.5 mm,以承受23.2 MW/m2的峰值热流密度;在此基础上,计算了不同扫射场下的导流靶温度场,分析了全钨导流靶模型的可行性。本文的研究可为今后高压水管柱分流靶的设计提供参考。
