AbstractThe present paper reports on the structural and tribological studies of MoSx films in the thickness range of 3-4000 Å bombarded with inert-gas ions in the hundred-keV energy range. It has been shown that it is possible to amorphize MoS1.8 crystalline films with 400-keV Ar ions at a dose of lxl016 ions/cm2 Contrary to previous studies, there is evidence for both a lowfriction coefficient and an increased sliding life of sputtered MoSx films when amorphized by the ion-bombardment technique. The paper will discuss the influence of ion dose and tribological differences between bombarded and nonbombarded MoSx films. With the availability ofhigh-intensity ion beams in the mA range, the possibility of a direct ion synthesis of a molybdenum surface with high-intensity sulphur-ion beams will be discussed, and friction measurements of these systems will be presented.

The Moment

A Zn2SiO4:Mn phosphor sample was bombarded by H+, H−, O−, O+, O2+, and O2− ions. In the energy range studied (10 < E < 90 keV), the ionoluminescence intensity was independent of the charge on the ion at the moment of impact. When the phosphor was bombarded by a molecular ion (H2, N2, O2, or CO2), the light output was less than the sum of the light outputs of the atomic constituents of the molecule at the same velocity.

AbstractThe experiment SONG (SOlar Neutron and Gamma rays) for the low altitude satellite CORONAS-I is described. The instrument is capable to provide gamma-ray line and continuum detection in the energy range 0.1 – 100 MeV as well as detection of neutrons with energies above 30 MeV. As a by-product, the electrons in the range 11 – 108 MeV will be measured too. The pulse shape discrimination technique (PSD) is used.
