The capability of plasma drag small space debris accelerator is affected by many factors such as charging condition,input gas content, the triggering process and so on. Through experiments the prime accelerating condition of was captured. The maximum velocity in different discharging energy is displayed in figure 1 and the utmost velocity is 15-18km/s. During the accelerating process interaction between particles and high pressure temperature and density plasma result in the crush of the particles. The crush is related to the discharging energy and the particle character. Figure 1. Particle velocity varies with discharging energy Figure 2. Particle diameters varies after been accelerated
