The general objective of this program has been to design a switch suitable for use in inductive energy storage power supplies. This switch consists of two major components, one for inductor charging bypass switch and one for high voltage direct current interruption interrupter tube. Within the general objective of this program, there are six primary tasks 1 evaluate the various bypass switch candidates and make a selection, 2 design the selected bypass switch, 3 design the interrupter tube for operation at the 100 KV, 20 KA, 5 Hz level. 4 perform a thermal analysis for the complete switch system, 5 determine the range of operating parameters scaling study, and 6 perform a systems study to determine the various means of interconnecting switch modules. Task 6 was expanded to include an evaluation of the relative merits of inductive versus capacitive storage. The three kinds of mechanical switch mechanisms evaluated were rotary, reciprocating, and torsional. The torsional mechanism was chosen primarily because of its potential ability to operate at repetition rates 5Hz. A switch based on this principle along with an interrupter tube have been designed for operation at the required levels.
