27. The high-density core of compensating Hminus beams

Dan Faircloth (UKRI STFC ISIS)

9/22/26, 3:45 PM

Invited

Recent particle in cell simulations of space change compensation in high current Hminus beams clearly demonstrate the formation of a high-density core in space charge compensating Hminus beams. Evidence of this phenomena has also been experimentally observed.

38. DESIGN OF A NEGATIVE OXYGEN BEAMLINE FACILITY FOR EXPERIMENTAL VERY LOW EARTH ORBIT SIMULATION

Lasse Voigt (Institute of Space Systems - University of Stuttgart)

9/22/26, 4:10 PM

Invited

There is a rapidly growing interest in operating satellites in very low Earth orbits (VLEO, $200$-$450$ km). These orbits support efficient communication and Earth observation and offer short post-mission lifetimes due to rapid reentry, reducing the risk of orbit contamination compared to conventional LEO ($>500$ km). The environment is dominated by atomic oxygen, and atmospheric drag and...
