ABSTRACT:
A high energy level electronic device is segregated into source diode and utilization diode portions, portions which may also be identified as cathode and main diode portions, respectively. The cathode diode portion is operated at a low voltage such that closure velocity effects therein although present, are minimized. A current of electrons, generated by in cathode diode plasma is fed to the second diode through an anode screen portion of the cathode diode. In this arrangement, since there are electrons, but no plasma cathode present in the main diode, no closing problem occurs therein. In this arrangement, therefore the cathode diode is effectively a source of current for the main diode and is operated at minimal voltage to enable the provision of current for a maximum length of time prior to closure effect terminations. The main diode is separated from the plasma and therefore may be operated at any arbitrarily high voltage free from closing effects, which remain isolated and controlled in the cathode diode. Separate pulse forming network energization of the cathode and main diode portions of the device are also disclosed.
