本文以石墨偏滤器靶板材料为例，用喷气或杂质注入对偏滤器靶板前等离子体温度进行控制，根据偏滤器等离子体的各种变标关系及石墨靶板被（物理溅射、化学溅射及辐射增强升华等过程）腐蚀的程度，优化了ＦＥＢ偏滤器靶板前等离子体温度和靶板运行温度。对于运行温度为１２００Ｋ，等离子体温度约为３２ｅＶ，靶板腐蚀速率可以控制在３ｃｍ／燃烧年以下，可大大增加靶板的寿命
In this paper, the target material of graphite divertor is taken as an example to control the temperature of the plasma in front of the divertor target with jet or impurity injection. According to various scaling relations of divertor plasma and graphite target (physical sputtering, chemical splashing Radiation and enhanced sublimation process, etc.) the degree of corrosion, optimized FEB divertor target plate before the plasma temperature and the target plate temperature. For the operating temperature of 1200K, the plasma temperature is about 32eV, the target plate corrosion rate can be controlled at 3cm / burn years, can greatly increase the life of the target plate
