DESIGN AND EVALUATION OF AN ION BEAM DELAY LINE.

Abstract

The theory and evaluation of a signal delay technique based on the travel time of an ion beam through an equipotential drift space filled with plasma are examined. Attention is given to plasma potential distribution and the control of particle trajectories by the use of magnetic and electrostaticsheath focusing. Emission characteristics of nickel and tungsten in a cesium environment, sheath phenomena, spacecharge neutralization, design data, construction techniques and evaluation tests are described in detail. Results indicate the basic soundness of the ion beam delay line concept. Ultimate characteristics of a tube using this technique could reasonably include (1) bandwidths from d. c. to 40 M. C. or higher, (2) voltage controlled delay from several microseconds to a millisecond, (3) low insertion loss and (4) a noise level no greater than that due to the random fluctuation of ion current.
