HL-2M装置真空系统调试运行

Engineering commissioning of HL-2M vacuum system

在装置初步建成阶段,有序地开展真空系统的调试内容梳理,制定合理的调试步骤和调试方案,有利于装置各系统的功能确认和故障排除,高效地开展各系统协同运行,为HL-2M装置初始等离子体放电提供装置辅助系统层面的放电条件准备。装置真空系统主要涉及超高真空抽气系统、器壁处理系统和送气加料系统等。基于制定的联调目标,针对HL-2M装置真空相关系统开展了界面关系梳理、子系统调试方案制定、系统工程联调步骤和方案的拟定等工作,通过联调完成了装置在真空获得、壁处理、加料等方面的条件准备,为初始放电提供了基本保障。

In the phase of initial completion of the device,the clarification on the items of engineering commissioning of vacuum and the development of reasonable commissioning scheme are conducive to the functional confirmation,troubleshooting,and the efficient coordinated operation of various systems.And it can prepare discharge conditions for the initial plasma discharge of HL-2M tokamak.The vacuum system of device consists of the ultra-high vacuum pumping system,the wall conditions and the gas injection system.Based on the defined objective,the interface sheets are sorted out,and the commissioning schemes and schedules are formulated for each subsystem and integrated system.The preparation of the vacuum environment,first wall and fueling of the device has been completed,and it provides essential conditions for the first plasma of HL-2M tokamak.
