| Abstract: | The density, drift velocity and reproducibility of the plasma produced by a cableplasma gun array have been measured with a charge collector array. The plasma is used to prefilla coaxial plasma-opening switch with a conducting time approaching 0.4μs. The reproducibilityof the plasma source in subsequent shots is better than 5%. Near the gun nozzle and the oppositeelectrode, the plasma density amounts to 1015cm-3, which is 2 times to 3 times that in the gapbetween the two coaxial electrodes. A plasma drift velocity of about 2.4 cm/μs is observed fromthe time of flight of the charged particles. Both plasma density and drift velocity increase almostlinearly with the rise in charge voltage. |
