Journal ArticleDOI
Laboratory detection of organic dust with the Cassini-CDA instrument
TL;DR: In this article, the authors used the Heidelberg dust accelerator facility to shoot micron sized carbon and latex particles on the engineering models of the space experiments, and the mass spectra achieved show sequences of broad peaks which are attributed to cluster ions of hydrocarbons.
Journal ArticleDOI
Large area mass analyzer
TL;DR: A new time-of-flight spectrometer for the chemical analysis of cosmic dust particles in space has been simulated by Simion 7.0 as mentioned in this paper, which is based upon impact ionization.
Proceedings ArticleDOI
Study of Hypervelocity Impact Plasma Expansion
Nicolas Lee,Sigrid Close,David Lauben,Ivan Linscott,Ashish Goel,Theresa Johnson,Ralf Srama,S. Bugiel,Anna Mocker +8 more
TL;DR: In this paper, a suite of RF, optical, and plasma sensors were used at the Max Planck Institute for Nuclear Physics to measure impact-generated plasma, which indicated a dependence on target electrical bias and material.
Proceedings ArticleDOI
Detection and Analysis of RF Data from Hypervelocity Impacts
Theresa Johnson,Ivan Linscott,Sigrid Close,David Strauss,Nicolas Lee,Richard Cosmo Adamo,Anna Mocker,Ralf Srama,S. Bugiel +8 more
TL;DR: In this article, ground tests were performed at the Max-Planck Institute fur Kernphysik Van de Graaff accelerator in Heidelberg, Germany to explore radiofrequency (RF) emission associated with hypervelocity particle impact induced plasma.
Journal ArticleDOI

TL;DR: The Cosmic Dust Analyzer (CDA) as mentioned in this paper measured the interplanetary, interstellar and planetary dust in our solar system since 1999 and provided unique discoveries, including the discovery of large reservoirs of liquid water (oceans) below the icy crust of Enceladus.
