An interstellar energetic and non-aqueous pathway to peptide formation
Alfred Thomas Hopkinson, Ann Mary Wilson, Joe Pitfield +13
The origin of the molecular building blocks of life is a central question in science. A few -amino acids such as glycine, the simplest proteinogenic amino acid, have been detect…
Bombardment of CO ice by cosmic rays: I. Experimental insights into the microphysics of molecule destruction and sputtering
Alexei V. Ivlev, Barbara M. Giuliano, Zoltán Juhász +12
We present a dedicated experimental study of microscopic mechanisms controlling radiolysis and sputtering of astrophysical ices due to their bombardment by cosmic ray ions. Such io…
Sulfur Ion Implantations Into Condensed CO2: Implications for Europa
D. V. Mifsud, Z. Kaňuchová, P. Herczku +12
The ubiquity of sulfur ions within the Jovian magnetosphere has led to suggestions that the implantation of these ions into the surface of Europa may lead to the formation of SO2.…
Energetic Electron Irradiations of Amorphous and Crystalline Sulphur-Bearing Astrochemical Ices
Duncan V. Mifsud, Péter Herczku, Richárd Rácz +10
Laboratory experiments have confirmed that the radiolytic decay rate of astrochemical ice analogues is dependent upon the solid phase of the target ice, with some crystalline molec…
A novel numerical tool to study electron energy distribution functions of spatially-anisotropic and non-homogeneous ECR plasmas
B. Mishra, A. Pidatella, S. Biri +5
A numerical tool for analysing spatially anisotropic electron populations in electron cyclotron resonance (ECR) plasmas has been developed, using a trial-and-error electron energy…
Status of the Bio-Nano electron cyclotron resonance ion source at Toyo University
T. Uchida, H. Minezaki, S. Ishihara +8
In the paper, the material science experiments, carried out recently using the Bio-Nano electron cyclotron resonance ion source (ECRIS) at Toyo University, are reported. We have in…
Synthesis of endohedral iron-fullerenes by ion implantation
H. Minezaki, S. Ishihara, T. Uchida +7
In this paper, we discuss the results of our study of the synthesis of endohedral iron-fullerenes. A low energy Fe+ ion beam was irradiated to C60 thin film by using a deceleration…
Fullerene-rare gas mixed plasmas in an electron cyclotron resonance ion source
T. Asaji, T. Ohba, T. Uchida +8
A synthesis technology of endohedral fullerenes such as Fe@C60 has developed with an electron cyclotron resonance (ECR) ion source. The production of N@C60 was reported. However, t…
Two-frequency heating technique at the 18 GHz electron cyclotron resonance ion source of the National Institute of Radiological Sciences
S. Biri, A. Kitagawa, M. Muramatsu +6
The two-frequency heating technique was studied to increase the beam intensities of highly charged ions provided by the high-voltage extraction configuration (HEC) ion source at th…
Fast camera studies at an electron cyclotron resonance table plasma generator
R. Rácz, S. Biri, P. Hajdu +1
A simple table-size ECR plasma generator operates in the ATOMKI without axial magnetic trap and without any particle extraction tool. Radial plasma confinement is ensured by a NdFe…
Experiments with biased side electrodes in electron cyclotron resonance ion sources
A. G. Drentje, A. Kitagawa, T. Uchida +2
The output of highly charged ions from an electron cyclotron resonance ion source (ECRIS) consists of ionic losses from a highly confined plasma. Therefore, an increase of the outp…
