The plasma edge of the CASTOR tokamak was investigated using a thermal lithium beam and electrical probes. The density profiles in the scrape-off layer (SOL) obtained by means of the lithium beam technique clearly reflect the particular limiter confi

Investigations of ion induced electron emission are made when (001) cleavage surfaces of some alkali halides (KBr, KCl, NaCl, LiF) are bombarded with He + , Ne + , Ar + , Kr + , and Xe + ions in the energy range 1,5–25 keV at normal incidence and a

If clean metal surfaces are bombarded with energetic ions in the keV range the predominant contribution to the sputtered flux are neutral metal atoms in the electronic ground state. It is well established that a drastic change in the composition of t

Eletron yields are measured when atomically clean (III) surfaces of Ge, GaAs and GaP are bombarded with Ne+, Ar+ and Kr+ ions in the energy range 2–25 keV. Energy distributions of the released electrons from these materials and Si are received. The

All arrangements that are used in practice to measure very small ion currents in mass spectrometry are based on the principle of the ion-electron converter. Counting losses occur when the pulses originating from the ions on the converter plate are co

During the last fifteen years notable advances have been made in the investigation of electron emission from solids caused by bombardment with ions having a wide kinetic energy range. These advances concern measurements of the dependence of the elect

Electron yields are measured when a Si-(111)-surface is bombarded with He + , Ne + , Ar + and Kr + ions in the energy range 1.5–25 keV. It is shown that, as in the case of metallic targets, the electron yield is strongly dependent on the coverage o
