Abstract: The charge of charged particles moving on the bottom plate is studied by using DC discharge to produce uniform plasma. The relative velocity of particle motion and other parameters are obtained by analyzing the collision trajectory of charged particles, and the charged quantity of particles is obtained. The experimental results provide a basis for further study of the complex motion of charged particles in dusty plasma.

Key words: plasma, particle collision, charge
