“…PIREB has been applied to the treatment of flue gases, water, and contaminated waste. [25][26][27] Furthermore, it can simulate the irradiation environment on Europa's surface by keeping a low temperature inside the irradiation chamber. In a previous study, the introduction of the color centers and their measurements was carried out using NaCl single crystals as targets at room temperature.…”

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.

“…In addition it has the advantage of processing at quite low temperatures [5] and operating almost instantly. A variety of non-thermal atmospheric pressure plasma methods have been employed for the treatment of VOCs in many studies [6], such as electron beam [7], pulsed corona [8][9][10][11], dielectric barrier [12], dielectric packed bed [13] and hybrid plasma-catalyst methods [14]. These studies have shown the influence on VOC conversion of various experimental parameters such as temperature or gas composition [15].…”

Gaseous naphthalene has been removed by air plasma generated by pulsed corona discharges at 100 °C (LSPM) and dielectric barrier discharges (DBD) up to 250 °C (LPGP) in different reactors geometries. Naphthalene has been chosen as one of unburned hydrocarbon present in exhaust gas engine during the cold start of vehicles. The comparison between the different discharge geometries has been possible using the specific input energy (SIE) as relevant parameter for pollutant removal process control considering the differences in the electrical characteristics and the differences of gas flow. The best naphthalene degradation is obtained in the wire-to cylinder (WTC) corona discharge and the stem-to-cylinder DBD with an energy cost β respectively of 10 and 20 J L −1 . The main by-products issues of the naphthalene oxidation are CO 2 and CO reaching 45% in Multi-Pin-to-Plan corona discharge. We detected polyaromatic hydrocarbons in the gas phase (few ppm) and in the solid phase deposited in the reactors. The introduction of water in the discharges promotes the naphthalene degradation by OH-atom, which has better oxidising power than O-atom in dry air.

“…19) Initially, the PIREBs from ETIGO-III have been studied with the aim of characterizing the pulsed beam itself. [20][21][22] Now this work has been extended so that the PIREBs have been applied to flue gas [23][24][25] and water [26][27][28] treatment. With the pulsed electron beam, these treatment efficiencies were found to be close to and higher than those by undertaken by DC accelerators.…”

To simulate the burst irradiation environment of Europa, single crystals of NaCl were irradiated by pulsed intense relativistic electron beams (PIREBs) with a peak energy of 6 MeV, a current of −800 A, and a pulse width of 70 ns. After irradiation, the optical absorption of the samples was measured, and results indicated that the irradiation induced F-and F 2 -centers. The density of F-centers was estimated to be 8.9 × 10 16 cm −3 from 1 shot of PIREB irradiation with 6 MeV. The absorbed energy to form F-centers by PIREB was comparable but slightly higher than those induced by conventional direct current accelerators. The effect of pulsed heating, which should be taken into account for the detection of NaCl on Europa, is discussed.
