摘要

中性束注入是托卡马克主要的辅助加热手段。目前先进实验超导托卡马克中性束注入（Experimental Advanced Superconducting Tokamak-Neutral Beam Injection，EAST-NBI）装置采用的是正离子源，运行过程中离子源的部分部件有很大的热沉积，其中反向电子吸收板最为严重。经实验研究，当束功率为3.5 MW时，沉积在反向电子吸收板上的平均功率密度高达4.4 MW

，有着较大的换热负担。为探究反向电子吸收板的极限运行时间，采用数值模拟的方法，对反向电子吸收板在不同束功率、冷却水水压等多种工况进行了计算。结果表明，电子吸收板随着束功率的增大，换热负担加重、换热效果变差，通过增压泵提高冷却水入口压力一定程度上可以提高换热能力，使其极限运行时间延长。对该课题的研究可以指导EAST-NBI的运行，以保证离子源安全、稳定工作，此外还为反向电子吸收板的进一步结构优化奠定理论基础，对发展长脉冲、高功率的离子源具有重要意义。

Abstract

Background

Neutral beam injection is one of the main auxiliary heating methods in controllable nuclear fusion experiment. The positive ion source is adopted in the EAST-NBI (Experimental Advanced Superconducting Tokamak-Neutral Beam Injection) device

and during its operation

there is a large energy deposition on ion source components

especially on the electron dump. According to previous research

when beam power is 3.5 MW

the average power density deposited on electron dump is around 4.4 MW

#183;m

-2

which may cause great burden for its heat transfer capacity.

Purpose

Research on the heat transfer conditions of electron dump is of great significance.

Methods

A numerical simulation method is adopted to calculate the heat transfer effect with the change of beam power and inlet pressure of cooling water

and the maximum operating time of electron dump is obtained.

Results

The results show that the heat transfer effect decreases with beam power growth

and by enhancing the inlet pressure of cooling water via booster pump

heat transfer capacity gets better to some extent

which can extend the maximum operating time of electron dump.

Conclusion

This research can guide EAST-NBI ion source to operate safely and steadily. Moreover

it can lay a foundation for increasing heat transfer capacity via structure optimization in future work

which is meaningful for the development of long pulse and high power ion source.
