A 2 MV Van de Graaff accelerator as a tool for planetary and impact physics research

Abstract: Investigating the dynamical and physical properties of cosmic dust can reveal a great deal of information about both the dust and its many sources. Over recent years, several spacecraft (e.g., Cassini, Stardust, Galileo, and Ulysses) have successfully characterised interstellar, interplanetary, and circumplanetary dust using a variety of techniques, including in situ analyses and sample return. Charge, mass, and velocity measurements of the dust are performed either directly (induced charge signals) or indirec… Show more

“…An area of continued interest for an understanding of problems ranging from atmospheric chemistry to astrophysical phenomena to industrial applications pertains to the impact phenomena of nanoparticles. Theoretical and experimental studies of nanoparticle-surface collisions at both low and high velocity ranges continue to be reported [2][3][4][5][6][7]. There is a large body of work on hypervelocity impact phenomena dating back to the early 1960's motivated by the need to understand the effect of cosmic dust and micrometeoroid impacts on space vehicles.…”

“…For our experiments we used the modified 2 MV Van de Graaff accelerator (Mocker et al, 2011), operated by the University of Stuttgart and located at the Max-Planck-Institut für Kernphysik. Here, positively charged dust grains, with sizes from 50 nm up to 5 lm, are accelerated via an electrostatic field of $2 MV to hypervelocity speeds between 1 and 100 km s À1 .…”
