摘　　要：根据半空间宽能谱太阳风离子探测分析器的地面标定要求,设计了一套多功能地面标定系统。该系统可模拟出探测器标定实验所需的空间等离子体环境,并具有真空室内部压强监控、离子束流衰减和使平行处理、离子束流监测(截面分布监测、强度监测和能量监测)等标定实验辅助功能。实验表明:该地面标定系统的各项功能和性能指标满足设计要求。According to the ground calibration requirements of the half-space-entrance and wide-spectrum ion analyzer for solar wind,a multifunctional ground calibration system is designed. The system can simulate the space plasma environment required for the calibration experiment of the analyzer. And it has some auxiliary functions for the calibration experiment such as vacuum chamber pressure monitor,ion beam current attenuated and paralleled treatment,ion beam monitor(section distribution monitored,strength monitored and energy monitored). The experimental results show that the functions and performance indexes of the ground calibration system meet the design requirements.
