ELECTRICAL EXPLOSION OF WIRE IN AIR AND VACUUM (ELEKTRICHESKII VZRYV PROVOLOCHKI V VOZDUKHE I VAKUUME),
Abstract
Experiments on the electric explosion of copper wire in air and vacuum were conducted in order to observe the difference in the explosive processes in these two media, and appreciable differences were noted. Spectroscopic studies of time-resolved plasma radiation were made, and the volt-ampere characteristics of the discharge in the initial stage of the explosion were determined. Experiments were also performed in order to study the process of expansion of the plasma cloud in a vacuum, and some plasma parameters were measured. It was found that the plasma expansion processes are less stable in a vacuum than in air. It is concluded that the explosion of the wire in a vacuum, despite a substantial complexity of the phenomenon as a whole, permits the study of a series of the physical properties of a dense plasma expanding in a vacuum.
