“…With regard to material surface modification [8,9], ion implantation of semiconductor [10][11][12], the uniformity of ion beam current density and ion beam stability determine the quality of the modified material or the semiconductor. There are many factors which influence the uniformity of ion beam current density and ion beam stability.…”

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.

“…With these PIII systems, the nitriding of carbon steels [21], and different types of stainless steels [22] were investigated. Another related concept used in surface nitriding is the Ion Beam Surface Treatment (IBEST) [23] in which high energy, high power nitrogen pulsed ion beams (generated with a magneticallyinsulated ion diodes) are deposited on the target surfaces. With this concept different types of steels and Ti alloys have been successfully nitrided [24].…”

“…In order to meet the requirements of research and industrial application, a number of IPIB sources [11][12][13][14] have been developed so far for different applications of IPIBs. The magnetically insulated ion diode ͑MID͒ is one of the most sophisticated one and uses a magnetic field perpendicular to the accelerating electric field to suppress the electron flow and enhance ion flow.…”

Intense pulsed heavy ion beam is expected to be applied to materials processing including surface modification and ion implantation. For those applications, it is very important to generate high-purity ion beams with various ion species. For this purpose, we have developed a new type of a magnetically insulated ion diode with an active ion source of a gas puff plasma gun. When the ion diode was operated at a diode voltage of about 190 kV, a diode current of about 15 kA, and a pulse duration of about 100 ns, the ion beam with an ion current density of 54 A/cm(2) was obtained at 50 mm downstream from the anode. By evaluating the ion species and the energy spectrum of the ion beam via a Thomson parabola spectrometer, it was confirmed that the ion beam consists of nitrogen ions (N(+) and N(2+)) of energy of 100-400 keV and the proton impurities of energy of 90-200 keV. The purity of the beam was evaluated to be 94%. The high-purity pulsed nitrogen ion beam was successfully obtained by the developed ion diode system.
