Research and Development on L-Band Crossed-Field Amplifier Chain
Abstract
New versions of both driver and power tubes were designed, and construction of these tubes was started. Studies were made of different magnetic circuit designs to determine how tubes could best be mounted in a phased array. It was concluded that a fixed array of permanent magnets with removable tubes made largely of non-magnetic material is preferable to combined tube and permanent magnet packages. Initial tests were made on the incorporation of a non-reciprocal ferrite attenuator on the slow wave circuit. While these tests show promise, they also indicate that a number of difficult problems must be solved to obtain a satisfactory non-reciprocal attenuator. Procurement of phase measuring equipment and life test equipment was started. A study of the relative costs of one antenna element per tube versus several elements per tube was conducted with the tentative conclusion that several elements per tube would be cheaper if the necessary high power phase shifters could be made available at reasonable cost.
