Journal ArticleDOI
Cassini finds molecular hydrogen in the Enceladus plume: Evidence for hydrothermal processes.
J. Hunter Waite,Christopher R. Glein,Rebecca Perryman,Ben Teolis,Brian Magee,Greg Miller,J. Grimes,Mark E. Perry,Kelly E. Miller,Alexis Bouquet,Jonathan I. Lunine,Tim Brockwell,Scott Bolton +12 more
TL;DR: The Ion Neutral Mass Spectrometer onboard the Cassini spacecraft is used to detect molecular hydrogen in the plume of escaping material on Enceladus, finding that the most plausible source of this hydrogen is ongoing hydrothermal reactions of rock containing reduced minerals and organic materials.
Journal ArticleDOI
Chemical interactions between Saturn's atmosphere and its rings.

Johnson,Wei-Ling Tseng,Orenthal J. Tucker,W-H. Ip +28 more
TL;DR: The Cassini Ion Neutral Mass Spectrometer (INMS) measured the composition of Saturn’s upper atmosphere and its chemical interactions with material originating in the rings, finding a large mass of infalling material that has implications for ring evolution.
Journal ArticleDOI
A Revised Sensitivity Model for Cassini INMS: Results at Titan
B. D. Teolis,Hasso B. Niemann,J. H. Waite,David A. Gell,Rebecca Perryman,Wayne Kasprzak,Kathleen Mandt,Roger V. Yelle,A. Y. Lee,F. J. Pelletier,Greg Miller,D. T. Young,Jared Bell,Jared Bell,Brian Magee,E. L. Patrick,J. Grimes,Gregory Fletcher,Véronique Vuitton +18 more
TL;DR: In this article, the authors presented a new INMS instrument sensitivity model, obtained by re-analyzing the capture and transmission of neutral gas through the instrument, and the detector gain reduction during pre-launch testing.
Proceedings ArticleDOI

TL;DR: In this paper, the authors describe a superconducting, laser-photocathode RF gun and an accelerator cavity capable of producing low emittance (about 1 micron rms normalized) one nano-Coulomb bunches at currents of the order of one ampere average.

TL;DR: In this article, the physics interest in a luminosity upgrade of RHIC requires the development of a cooling-frontier facility, and detailed calculations were made of electron cooling of the stored RHIC beams.
