“…A novel one-turn capacitor-coil target was introduced by Korobkin [27] in 1979 and developed by others theoretically and experimentally [28][29][30][31]. Recently, double-turn capacitorcoil targets were used [32][33][34] to investigate fast MR in low-β plasma.…”

Push and pull magnetic reconnection (MR) experiments using a high-power laser irradiating a capacitor target with the plates connected by a pair of coils are carried out. During the beginning (end) stages of the laser-target interaction that creates a hot plasma in the region, the rise (fall) of the coil currents generates expanding (contracting) magnetic fields that reconnect in the mid-plane between the coils, resulting in push (pull) MR. Proton radiography and proton ray-tracing simulation are used to track the evolution of the magnetic field distribution. The proton aggregate and void characteristics between the coils are related to the opposite current-sheet current during the push and pull MR stages. The directions of the hot plasma electron outflows during these two MR phases are obtained by monitoring the soft X-ray emission. Our results suggest that the double-coil capacitor target may be useful for laboratory modeling of fast MR and related phenomena in astrophysical plasmas.

The propagation of a metal plasma flow in a transport system with a curvilinear magnetic field was studied experimentally. The flow was generated by a pulsed vacuum arc discharge with a composite (W + Fe) cathode. The ion energy measurements at the transport system output showed that all ion components were accelerated up to equal energies per charge unit, about 150 eV and 320 eV in the outer and inner areas of the curved plasma flow, respectively. The spatial separation of the atoms of the cathode material was measured at the system output by x-ray fluorescence spectrometry. The ions of the lighter element (Fe) were concentrated in the inner part of the cathodic plasma flow deflected by the magnetic field while the distribution of the heavy element (W) was substantially shifted toward the outer area of the flow. The maximum mass separation efficiency reached 45, the effective value being 7.7. Such a system is promising for use in plasma technology for reprocessing spent nuclear fuel, namely for the separation of the heavy radioactive fission product from nuclear waste.
