“…The designed thermal imaging procedure was used for studying the PIB, formed by an ion diode with external magnetic insulation [16]. The studies were performed on the ТЕМП 4M accelerator with the use of the same diagnostic equipment as for studies of an ion diode with the self magnetic insulation.…”

“…These pulsed ion beams can induce strong flash thermal shock effects on the target surface, inducing rapid melting and re-solidification in a depth of several µm with a rate up to 10 8 -10 10 K/s with shock waves generated and propagated into the deeper region of the target [14,15]. Material processing, such as surface melting [16,17], improvement in mechanical and anti-corrosion properties [18][19][20] can be achieved in the meantime. The surface treatment with IPIB can handle larger areas compared with laser beams for its relatively larger beam diameter (typically in several cm) [21][22][23], and surface processing can be done with higher speed and uniformity.…”

Intense pulsed ion beam irradiation on IN718 superalloy prepared with selective laser melting as an after-treatment for surface melting is introduced. It is demonstrated that intense pulsed ion beam composed of protons and carbon ions, with a maximum current density of 200 A/cm2 and a pulse length of 80 ns, can induce surface melting and the surface roughness changes significantly due to the generation of micro-defects and the flow of the molten surface. Irradiation experiments and thermal field simulation revealed that the energy density of the ion beam plays a predominant role in the irradiation effect—with low energy density, the flow of molten surface is too weak to smooth the fluctuations on the surface. With high energy density, the surface can be effectively melted and smoothened while micro-defects, such as craters, may be generated and can be flattened by an increased number of pulses. The research verified that for the surface melting with intense pulsed ion beam (IPIB), higher energy density should be used for stronger surface fluidity and a greater pulse number is also required for the curing of surface micro-defects.

“…For a total ion beam energy of (80-90) J per pulse, 500 J additional energy is required to generate the magnetic field [5]. With its high stability and high efficiency (20-40)%, the external magnetic insulated diode [6,7] is widely applied in scientific researches.…”

An experimental study of a semi-cylindrical external magnetically insulated diode using a polyethylene film and the No. 25 transformer oil acting as anode discharging materials is carried out. The luminescence images of anode plasma and the ion beam current density are acquired using an intensity charge-coupled detector (ICCD) camera and a calibrated Faraday, respectively. The experimental results show that the ion beam current density of the No. 25 transformer oil is higher than that of the polyethylene film. The maximum ion beam current densities at the focus point of the No. 25 transformer oil and the polyethylene film are 325 A/cm2 and 310 A/cm2, respectively. Meanwhile, the lifetime of the No. 25 transformer oil is significantly longer than that of the conventional polyethylene film. The lifetime of the No. 25 transformer oil is about 5000 discharges, while that of the conventional polyethylene film is about 400 discharges. In addition, the ion beam current density of the No. 25 transformer oil is more stable than that of the polyethylene film, and the anode plasma of the No. 25 transformer oil is more uniform than that of the polyethylene film.
