Abstract
The theory, the estimated parameters, and the design features of the linear accelerator capable of accelerating charged dust particles 0.1–10 μm in diameter to velocities of 12 km/s are presented. The electrodynamical circuit of the accelerator is composed of 27 acceleration gaps, each of which is held at a potential of 20 kV. Particles are injected into the linear electrodynamical accelerator after preliminary acceleration in the linear electrostatic accelerator with an effective voltage of 145 kV. The total effective accelerating voltage is 670 kV. The total length of the accelerating sections is 3.62 m. The essential difference of this accelerator from the existing machines is that the drift tubes of the dynamical circuit are identical and that synchronism of particle motion with the voltage applied to the drift tubes is achieved by forming the accelerating voltage as a function of the particle velocity and specific charge. The measured performance data of the accelerator are presented.
