摘　　要：HL 2A装置上首次实现了偏滤器位形放电。采用专门研制的可在强磁场和强噪声环境下工作的快响应真空电离规对偏滤器室内的中性气体压强进行了测量,给出了HL 2A装置偏滤器有关结构的基础数据。初步研究了偏滤器位形和孔栏位形放电期间偏滤器室中性气体压强的特性。The first plasma with a divertor configuration in the HL-2A tokamak has been achieved. A fast ionization gauge capable of operating in a strong magnetic field and noisy environment has been developed to measure the pressure in the HL-2A divertor chamber. The divertor configuration parameters have been given, and initial study of the neutral gas pressure in the divertor chamber with and without the divertor configuration in the HL-2A tokamak has been made.
