Electronically adjustable nanosecond pulse generator utilizing storage diodes havingsnap-off characteristics

Claim 1

A PULSE GENERATOR COMPRISING: (A) A SOURCE OF ALTERNATING WAVES OF PRE-DETERMINED FREQUENCY, (B) A FIRST CHANNEL HAVING WAVES APPLIED THERETO FROM SAID SOURCE, SAID CHANNEL INCLUDING A STORAGE DIODE HAVING SNAP-OFF CHARACTERISTICS CONNECTED IN SAID CHANNEL TO PERMIT TRANSMISSION OF POSITIVE CURRENTS AND TO EFFECT A SHARP REDUCTION IN TRANSMISSION ABRUPTLY, BUT AT A TIME APRECIABLY AFTER ONSET OF APPLIED NEGATIVE CURRENTS AT SAID PRE-DETERMINED FREQUENCY, TO CREAT A FIRST WAVEFRONT, (C) A SECOND CHANNEL HAVING WAVES APPLIED THERETO FROM SAID SOURCE OF A POLARITY OPPOSING THOSE APPLIED TO SAID FIRST CHANNEL, SAID SECOND CHANNEL HAVING A SNAP-OFF STORAGE DIODE CONNECTED TO PERMIT TRANSMISSION OF NEGATIVE CURRENTS AND TO EFFECT A SHARP REDUCTION IN TRANSMISSION ABRUPTLY, BUT AT A TIME APPRECIAABLY AFTER ONSET OF POSITIVE CURRENTS AT SAID PREDETERMINED FREQUENCY TO CREATE A SECOND WAVEFRONT, (D) MEANS COUPLED TO AT LEAST ONE OF SAID CHANNELS TO TIME SAID SNAP-OFFS AT RELATIVELY DIFFERENT INSTANTS IN TIME WITHIN AN INTERVAL DURING WHICH THE AMPLITUDES OF SAID WAVES AT SAID RESPECTIVE DIODES ARE SUBSTANTIAL, AND (E) COMMON OUTPUT LOAD MEANS RECONNECTING SAID FIRST AND SECOND CHANNELS TO A COMMON OUTPUT TERMINAL WITH SUFFICIENT MUTUAL ISOLATION TO PERMIT THE CREATION OF INDEPENDENT WAVEFRONTS IN THE RESPECTIVE CHANNELS, SAID OUTPUT TERMINAL BEING SO PLACED WITH RESPECT TO SAID CHANNELS THAT WAVES PROPAGATING TO SAID OUTPUT TERMINAL IN THE RESPECTIVE CHANNELS WILL CANCEL IF SAID DIODES ARE ACTUATED RELATIVELY SIMULATEOUSLY OR LEFT UNACTUATED AND THAT A PULSE WILL BE SYNTHEZIED OR LEFT SAID SEPARATED WAVEFRONTS WHEN SAID DIODES ARE CAUSED TO SNAP OFF AT RELATIVELY DIFFERENT TIMES.
