Abstract等离子体驱动微小碎片加速器是地面模拟空间微小碎片超高速撞击实验的装置,决定其加速效果的是加速器同轴枪内等离子体轴向速度.采用发射光谱法研究等离子体轴向速度随放电电压和工作气体压强的变化关系.实验结果揭示:轴向速度随着放电电压的增大线性增加,随工作气压的增大而缓慢减小,与数值模拟结果符合.为进一步提高等离子体轴向速度,优化加速器提供了可靠依据.
Other AbstractPlasma driven micro-particle accelerator is a ground device for simulating impact effects of small debris in space.The particle velocity is determined mainly by axial velocity of plasma in a coaxial gun.Emission spectrometry is used to study the plasma axial velocity at different voltages and gas pressures.The experimental results indicate that axial velocity increases with the increase of discharging voltage,and doesnt change significantly with the pressure of working gas,which is consistent with the result of numerical simulation.This result is useful to improve the plasma axial velocity further,and provides an experimental basis for optimizing the accelerator.
