About the Electrodynamic Acceleration of Macroscopic Particles

Abstract

An electric charge is imparted to macroscopic particles, whereupon they are pre-accelerated in an electrostatic field by the high voltage U = 220 kV. Then the particles are accelerated by a traveling electromagnetic wave with the initial phase velocity lying in the range v/c = 1e-3 - 1e-5. Focusing the particles is provided by electrostatic doublets. At the acceleration length L = 20 m, the particles with Z/A = 2.3e-7 increase their velocity from v/c = 1e-5 to v/c = 1e-4.
