Interconnecting circuit for EBS diodes and method

An EBS source, for coupling energy to a load at a radio frequency operating range, wherein the source is of the type utilizing an electron beam to illuminate beam surfaces of plural EBS diodes capable of assuming first and second states in response to said excitation comprising electron beam means for alternatively illuminating said diodes in a predetermined manner, first and second EBS diodes arrayed to receive said beams, said diodes being electrically series connected in phase at said operating frequency range, said diodes each having a radio frequency generating state when illuminated and a back-biased state including a finite capacitance thereacross when non-illuminated, load coupling means connected across said series connected diode combination, a power supply, isolation means connected between said diode combination and said supply for providing voltage and current to each diode and providing isolation between said diodes and between said diodes and said supply at said operating frequency range, so that when said first diode is illuminated the radio frequency energy generated is coupled via the finite capacitance of the second diode to said load, and when said second diode is illuminated the radio frequency energy generated is coupled via the finite capacitance of the first diode to said load.
