Construction and operation of an electronic ram Billington, Ian James

Abstract

A model of an electronic ram was built and operated in order to examine experimentally the principle of this proposed accelerator for charged particles; The experimental work comprised several steps: production of a pulsed tubular electron beam; control of the axial velocity, space charge density, and cross section of the beam by a homogeneous longitudinal magnetic field; and use of a region of rapidly increasing magnetic field intensity to reduce suddenly to aero the axial velocity of the electrons, thereby converting electrokinetic energy of the beam to potential energy. This energy conversion was required to produce the "ram effect" (the raising of the front electrons of the beam to a high energy level.) The results obtained are in accordance with theory and indicate the existence of the ram effect.
