“…Experiments were carried out using an intense, pulsed power generator, ''ETIGO-II''. 12) The LIB was produced with a magnetically insulated ion-beam diode, in which the motion Using a polyethylene sheet as a flashboard anode, the proton content of the LIB was more than 75%, which was determined with an energy spectrometer. Table I summarizes the experimental conditions.…”

The extinction of large droplets in ablation plasma produced by intense pulsed ion-beam evaporation (IBE) has been proposed to improve the surface morphology of Al thin films on Si substrates. After the ion-beam irradiation of an Al target, a lot of spherical objects with diameters of approximately 20 to 100 µm were observed on the Al target surface, they are considered to be a possible origin of droplets commonly observed on Al thin films. However, the number of large droplets decreased with increasing distance between the Al target and Si substrate. The following model was considered to explain the obtained results. When a spherical object flies in the ablation plasma, it seems that the object fragments into small pieces or is evaporated. As a result, the number of large droplets decreases with increasing flight distance.

“…ETIGO-III is a pulsed intense relativistic electron beam (PIREB) accelerator that has been used for applications in materials science, high-power microwave generation, and intense X-ray generation. 24) A peak acceleration energy of 2 MeV, an output current of 5 kA, and a pulse width of 70 ns can be achieved. The acceleration voltage of up to 8 MeV can be obtained by connecting the irradiation cells.…”

In order to reproduce the irradiation environment of Europa, NaCl-0-2mol%KCl crystals were grown and irradiated with pulsed intense relativistic electron beams at RT and 77 K in the optical absorbance spectra. The peak wavelength of the F-center was shortened by decreasing the measurement temperature and the KCl content. This phenomenon can be explained by the changes of the lattice constant and utilized to determine temperature and KCl content in the sea of Europa.

“…A soil sample containing formaldehyde solution as the VOC is directly irradiated by a PIREB (2 MeV, 0.4 kA, 70 ns), and then the concentration of VOC diffused into a treatment chamber is investigated. In these experiments, a pulsed‐power generator, ‘ETIGO‐III’ 3, installed in the Nagaoka University of Technology, is used for generating the PIREB.…”

A volatile organic compound (VOC) contained in soil was treated by irradiation with a pulsed intense relativistic electron beam (PIREB). A treatment chamber was filled with the molded soil sample containing formaldehyde solution as a VOC, and was irradiated by a PIREB (2 MeV, 0.4 kA, 70 ns). The soil sample was a mixture of red and black clay representing the Kanto loam in Japan. The diffused formaldehyde of 64% is resolved by firing five shots of the PIREB at the initial concentration of 55 ppm. 
