Abstract:
In the course of the study of laser pumping techniques, Raytheon developed a reliable calorimeter technique to measure the transfer efficiency of the theta pinch in converting capacitively stored electrical energy to electromagnetic energy. It is shown, with the use of circuit measurements, that the efficient theta-pinch circuit decay consists of a two-stage circuit decay and that the inefficient theta pinch consists of a three-stage decay. Using the circuit decay data, a modified transfer efficiency measurement for a two-stage plasma circuit was developed that is approximately as accurate as the calorimeter technique, but very much faster and easier to make. These measurements have been used to evaluate the transfer efficiency of the theta-pinch in Argon at pressures of 2 and 5 Torr with different tube sizes and with different coupling impedances. Measurements have shown a transfer efficiency as high as 59 percent with present measurements. Spectral measurements show that the preionization techniques increase the continuum radiation with the small diameter tubes and are ineffective with the largest diameter tubes used. Author
