Abstract:

This report covers the work to build and evaluate an experimental Electromagnetic Amplifying Lens EAL at X-band which will demonstrate the practicality of the EAL principle, and to carry out a theoretical and experimental investigation of fabrication techniques and tube components necessary for the embodiment of the EAL principle in a practical super power millimeter wave oscillator or amplifier. During the quarter, a decision was reached to incorporate into the EAL a new cathode which would provide an accurate cathode-anode spacing. Design work proceeded toward this end and was largely complete by the end of January. Simultaneously, tests were conducted on the EAL at 5250 - 5650 Mcs to determine the effects of driving the tube at these frequencies. A post-operative analysis of the disassembled EAL indicated that severe arcing and melting of copper had occurred within the tube. There was, therefore, additional difficulty imposed upon the analysis of previous results. The cathode redesign was modified to eliminate arcing problems if possible. Author
