MACROPARTICLE LAUNCH VELOCITY CONTROL IN RAIL ACCELERATORS

The paper is devoted to the development of the method to increase the stability of the macroparticle launch velocity in the electromagnetic- rail accelerators for the simulation of space debris. The method is ba sed on the acceleration process control in the real time. The principl e of the accelerator control is in varying the armature current and ma croparticle acceleration with a circuit by-passing. The control algori thm with memory has been investigated. The acceleration process contro l reduces the effect of disturbances in accelerator parameters and ini tial conditions, as well as the effect of measurement errors upon the spread in launch velocities. The control algorithm efficiency is check ed by numerical modeling of operation of the laboratory rail accelerat or with plasma armature.
