MICROWAVE ELECTRONICALLY VARIABLE ION BEAM TIME DELAY DEVICE STUDY.

Abstract

The three major areas studied are (1) sources of ions to form beams; (2) focusing of ion beams; and (3) coupling RF signals on and off ion beams. Experiments on thermionic ion sources are described in which first results show that impregnated ion emitters having limited life can be fabricated by sintering together powered metals and alkali-metal-bearing minerals. Lithium-ion emission greater than 100 microamperes/sq cm has been obtained. Emitters yielding sodium and potassium ions have also been fabricated. A coupler employing a large number of klystron-type gaps is analyzed and it is argued that this would be suitable for ion beams since large transit angles (approximately 180 degrees) can be used. With regard to beam focusing, magnetostatic, electrostatic, and space-charge neutralization are considered. It is pointed out that Brillouin fields for most interesting cases of magnetic focusing would be prohibitively high. Conclusions and recommendations for the second-quarter effort are discussed.
