2. 1. The Neutral Particle Detector on the Mars and Venus Express missions

   Author : Alexander Grigoriev; Stas Barabash; Brian J. Anderson; Umeå universitet; []
   Keywords : Space and plasma physics; ENA imaging; exosphere; magnetosphere; Mars; Venus; solar wind interaction; Rymd- och plasmafysik; rymd- och plasmafysik; Space and Plasma Physics;

   Abstract : The Neutral Particle Detector (NPD) is a new type of instrumentation for energetic neutral atom (ENA) diagnostics. This thesis deals with development of the NPD sensor designed as a part of the plasma and neutral particle packages ASPERA-3 and ASPERA-4 on board Mars Express and Venus Express, the European Space Agency (ESA) satellites to Mars and Venus, respectively.

4. 2. Solar Wind Proton Interactions with Lunar Magnetic Anomalies and Regolith

   Author : Charles Lue; Yoshifumi Futaana; Stas Barabash; Urs Mall; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; the Moon; solar wind; magnetic anomalies; regolith; space physics; plasma physics; particle-surface interactions; mini-magnetospheres; energetic neutral atoms; Space Physics; rymdfysik;

   Abstract : The lunar space environment is shaped by the interaction between the Moon and the solar wind. In the present thesis, we investigate two aspects of this interaction, namely the interaction between solar wind protons and lunar crustal magnetic anomalies, and the interaction between solar wind protons and lunar regolith.
