We, Tuparev AstroTech in partnership with Astro Syteme Austria, present a next-generation Space Situational Awareness (SSA) system currently being created for the tracking and characterisation of satellites and space debris in the age of big-data ast

The electron emission yield is measured for impact of 3 keV electrons on polycrystalline aluminum, which is exposed to oxygen. At different oxygen gas pressures the yield is measured as a function of time. The oxygen pressure is in the range between

The electron emission yield was measured for impact of 3 keV electrons, 2 MeV H+, 4 MeV He2+ and 6 MeV O3+ ions on polycrystalline Al, Cu and Ag samples as a function of sample temperature in the temperature range of 25–450 °C. A significant influ

The kinetic electron yield was measured for the impact of 3 MeV He 2+ ions and 3 keV electrons on thin layers of Al on Cu, of Al 2 O 3 on Al, and of CeO 2 and CaF 2 on Si backings. The dependence of the yield on the layer thickness was determined. Fo

The electron emission yield was measured for the impact of 3 keV electrons and 2 MeV H+ ions on Al as a function of target temperature. A strong influence of the surface morphology was found. For annealed samples a linear decrease of the yield was ob

For 3 MeV He ++ and 3 keV electron projectiles the kinetic electron emission yield for copper layers of different thickness on an aluminum backing was measured. Since the electron emission yield of Cu is almost a factor of 2 higher than that of Al an

We describe a new setup for elastic recoil detection analysis (ERDA) using our recently developed particle identification method. Before the ions and elastic recoil atoms from the target reach a silicon surface barrier detector for energy analysis, t
