| 摘 要： | 根据已有的理论模型，推算出了HL-2A偏压偏滤器的理论电流为1．5kA、偏压电压为200V，并对HL-2A偏压偏滤器做出了初步设计。HL-2A装置采用偏压后，有可能降低L-H模转变阈功率，增加偏滤器等离子体密度、压强和滞留时间，改善约束，改善内外靶板功率沉积的非对称性，提高排灰效率及提高偏滤器性能。

| Abstract: | The current and voltage of a biased divertor for the HL-2A tokamak have been predicated according to the present theoretical model.They are about 1.5kA and 200V respectively.Initial engineering design of the biased divertor is also presented.Divertor biased voltage in the HL-2A tokamak may decrease the threshold power of L-H transition,increase the density,pressure and retention time of divertor plasma.It can improve plasma confinement and the asymmetry of deposition power between inboard target and outboard one,increase the pumping efficiency of fusion products and optimize the divertor performance. |
