“…The object of research was samples (30x15x3 mm) of technically pure magnesium which surface was mechanically burnished and polished using abrasive paper and diamond suspensions. The samples were studied using a TEMP-4M accelerator at an accelerating pulse duration τ =100 ns and an energy density J (J/cm 2 ) on the surface of the target such as: 0.5 (Δ =100 pulses), 1.5 (Δ = 100 pulses), and 2.5 (Δ =10 pulses), J/cm 2 [6]. The particle flux from a self-magnetically insulated vacuum diode operating in a two-pulse mode consists of carbon ions C n +I admixed with protons and corresponding neutrals.…”

“…Investigations were conducted at accelerator TEMP-4M (modification of accelerator TEMP-4 [17,18]) with the following parameters: the first impulse is negative (≈ 100 ns, 100-150 kV) and the second one is positive (80 ns, 250-300 kV). Beam composition: ions of carbon and protons, ion current density 10-150 A/cm 2 (for different types of diodes), pulse frequency 5-10 pulses per minute.…”

The results of an experimental investigation of the plasma dynamics in a magnetically insu- lated ion diode in bipolar-pulse mode are presented. The experiments were done at the pulsed TEMP-4M accelerator by formation of a first negative pulse (100 ns, 150-200 kV) and a second positive pulse (80 ns, 250-300 kV). The voltage-current diode characteristics were used to analyze the plasma behavior in the anode- cathode gap. It is shown that, during the first pulse, a discrete emissive surface is formed on the graphite potential electrode and a plasma forms by explosive-emission, which before the second pulse comes, fills the whole working surface of the electrode and spreads to the anode-cathode gap. An analytical expression is obtained for the total current in the cellular structure approximation. It is shown that the current build-up for a cathode surface with dis- crete emitting centers is described satisfac- torily by a modified Child-Langmuir formula wi- th a form factor decreasing from F = 6 to 1. It is found that, once plasma formation at the gra- phite potential electrode is complete and until the second positive pulse, the plasma speed is constant and equals 1.3 ± 0.2 cm/μs

“…This idea has also been proposed as a possible explanation for the observation of unusually rapid expansion of the anode plasma across the magnetic field in a magnetically insulated ion diode [4]. Additional confirmation that charge exchange neutrals are present in the beam is the spot formed by undeflected charge exchange neutrals in the center of Thomson spectrogram registered by the Thomson parabola spectrometer [5][6][7].…”
