Studies of dense plasmas in laser generated shock wave experiments Parfeniuk, Dean Allister


Two theoretical models were developed to predict the effect of conducting shells on electrodeless breakdown at low frequencies (<1 kHz). If glass shells containing gases at low pressures are immersed in an alternating electric field, of sufficient magnitude, these bulbs will emit pulses of light. Together the theoretical models predict the form of the calibration curves of these bulbs, which are plots of the pulse rate as a function of the magnitude of the applied field. Experimental verification of these models was observed. Furthermore, the surface conductivity of paxolin and neoprene was measured as a function of frequency in the range 40 Hz to 1 kHz.
