Plasma probes are well established diagnostic tools. They are not complicated, relatively
easy to construct and to handle. The easiest and fastest accessible parameter is their …

The floating potential of an emissive cylindrical probe in a plasma is calculated for an
arbitrary ratio of Debye length to probe radius and for an arbitrary ion composition. In their …

The region between a Maxwellian plasma source and a floating or current-carrying surface
is described by a static, one-dimensional collisionless kinetic sheath model. In the plasma …

At keV energies, many electronic processes contribute to the emission of secondary
electrons in the interaction of highly charged ions on surfaces. To unravel contributions …

The secondary electron yields as a result of highly charged ions impinging on clean Au
(111) and thin films of C 60 on Au have been measured. This has been done for film …

A copper sample facing an energy-resolved mass spectrometer is biased positively beyond
plasma potential in low-pressure argon plasma. Some ions are created in the sheath by …

Tungsten has recently been introduced as a new wall material for fusion, because it exhibits
favourably low sputtering yields and a very low tritium retention as compared to the …

To study and optimise negative ion production for the ITER neutral beam injectors, a test
facility is under construction in Padova with the aim of testing beam characteristics and to …

When energetic particles impinge on solid surfaces, a multitude of phenomena is observed.
Among them are erosion of material (ie sputtering), surface modifications, reflection or …

Thermonuclear fusion powers our universe and is a most promising option for electricity and
hydrogen fuel generation within a future sustainable and environmentally benign energy …
