Erosion Resistance of Carbon-Carbon Ion Optics

Journal of Propulsion and Power, 2001
A principal consideration in the design of ion thrusters for spacecraft propulsion is erosion of the downstream grid in the ion optics. Achieving adequate lifetime (10,000 h or more for many potential missions) without grid wear-through can impose signiŽ cant constraints on thruster performance.

Biological characteristics of carbon-ion therapy

International Journal of Radiation Biology, 2009
Radiotherapy using charged and/or high-linear energy transfer (LET) particles has a long history, starting with proton beams up to now carbon-ions. Radiation quality of particle beams is different from conventional photons, and therefore the biological effects of high-LET irradiation have attracted scientific interests of many scientists in basic and ...

[Particle therapy: carbon ions].

Bulletin du cancer, 2010
Carbon ion therapy is an innovative radiation therapy. It has been first proposed in the forties by Robert Wilson, however the first dedicated centres for human care have been build up only recently in Japan and Germany. The interest of carbon ion is twofold: 1) the very sharp targeting of the tumour with the so called spread out Bragg peak that ...

Ion implantation in tetrahedral amorphous carbon

Physical Review B, 1995
Tetrahedral amorphous carbon (ta-C) is a dense form of amorphous carbon with a structure consisting of a highly tetrahedral bonding network. Approximately 20% of the atoms in ta-C are ${\mathit{sp}}^{2}$ hybridized and the presence of these sites plays an important role in the electrical and optical properties of the material.
