“…The ion current portion of the total diode current does not exceed 10%; 12,13 in fact it is mainly electrons drifting in the A-K gap which contribute to the total diode current. We showed that the instability of the ion beam generation only weakly depends on the shot-to-shot variation in the total diode current, the standard deviation of the total current did not exceed 5%-7%.…”

In this paper we present the analysis of shot to shot reproducibility of the ion beam which is formed by a self-magnetically insulated ion diode with an explosive emission graphite cathode. The experiments were carried out with the TEMP-4M accelerator operating in double-pulse mode: the first pulse is of negative polarity (300-500 ns, 100-150 kV), and this is followed by a second pulse of positive polarity (150 ns, 250-300 kV). The ion current density was 10-70 A/cm(2) depending on the diode geometry. The beam was composed from carbon ions (80%-85%) and protons. It was found that shot to shot variation in the ion current density was about 35%-40%, whilst the diode voltage and current were comparatively stable with the variation limited to no more than 10%. It was shown that focusing of the ion beam can improve the stability of the ion current generation and reduces the variation to 18%-20%. In order to find out the reason for the shot-to-shot variation in ion current density we examined the statistical correlation between the current density of the accelerated beam and other measured characteristics of the diode, such as the accelerating voltage, total current, and first pulse duration. The correlation between the ion current density measured simultaneously at different positions within the cross-section of the beam was also investigated. It was shown that the shot-to-shot variation in ion current density is mainly attributed to the variation in the density of electrons diffusing from the drift region into the A-K gap.

“…7, obtained at d = 55 and 190 mm, in accordance with the following formula [12]: (1) where h m and h 0 are the maximum penetration depth and the residual imprint depth of a Vickers pyramid, respectively. This empirical parameter characterizes a relative recovery of the imprint after unloading and can be used to estimate the value of the yield point for the coating material, which in turn defines the crack ing susceptibility of the coating.…”

Titanium coatings are deposited on a Si substrate by their deposition from ablation plasma pro duced by irradiating a Ti target with high power ion beams. The dependences of the adhesion, nanohardness, Young's modulus, and friction coefficient on the distance between the sputtered target and the substrate and on the thickness of the coating are studied for thin film titanium coatings. The formation of a transition layer with an alternating content of Ti is found to increase coating adhesion.

“…The high-intensity pulsed ion beam (HIPIB) or intense pulsed ion beam (IPIB) technique has been developed for materials processing during the last two decades, where two kinds of applications are mainly evolved, i.e., surface modification of materials and syntheses of thin films and nanoparticles [1][2][3]. The principle of this technique is to induce surface remelting and/or ablation of materials by depositing a short pulse (,1 ms) of ion-delivered high-density energy (,10 2 J/cm 2 ) into a certain depth (,10 mm) dependent on the ion range in irradiated materials.…”

The high-intensity pulsed ion beam (HIPIB) technique is developed to treat metallic and ceramic surfaces to improve materials performance. The processing is based on the beam-material interactions: remelting and/or ablation of a top layer on the irradiated surfaces (extreme surface heating effect); subsequently, the molten states may be frozen at an ultra-fast re-solidification rate after termination of the ion beam pulse. Surface smoothing and reconstruction of titanium alloys and ZrO 2 -Y 2 O 3 coatings have been observed as one of the typical outcome under high-intensity pulsed ion beam irradiation. It is demonstrated that the changes in surface morphology may significantly contribute to the improvements of overall performance of the materials.
