Abstract—

The formation of plasma on the surface of a current-carrying electrode of a high-current facility when a current flows through it with a linear density of up to 4 MA/cm and is coated with lead foil or ceramic is studied. The propagation velocity of a dense plasma from a stainless steel electrode is 2–10 km/s, and when the electrode is coated with lead, it is 1–6 km/s. In these experiments, there is no load typical for such facilities—a source of intense X-ray radiation. The plasma propagation from ceramic-coated electrodes starts 200 ns later than that for metal electrodes.

载有兆安电流的表面的电爆炸

摘要-

研究了当电流以高达4 MA / cm的线密度流过并涂有铅箔或陶瓷时，大电流设备的载流电极表面上等离子体的形成。不锈钢电极中密集等离子体的传播速度为2-10 km / s，当电极涂有铅时，速度为1-6 km / s。在这些实验中，此类设备没有典型的负荷-强烈的X射线辐射源。陶瓷涂层电极的等离子体传播比金属电极的等离子体传播晚200 ns。
