*************************** ** THE GEM MESSENGER ** *************************** Volume 19, Number 5 April 30, 2009 ---------------------------------------------------------------------------- GEM 2009: Physical processes in the cusps: Plasma transport and energization ---------------------------------------------------------------------------- From: K.J. Trattner, N. Omidi and D. Sibeck, Conveners During the 2009 Summer GEM workshop in Snowmass Colorado, a number of sessions on the physical processes in the cusp will be held. The main objective of these sessions is to utilize observations, modeling, and theory of the cusp and its role in particle acceleration and plasma transport to assess the current status of the field and forge collaborative efforts towards addressing outstanding issues in the future. Based on the topics in earlier years and the discussions during the mini-workshop held during the 2008 Fall AGU, we plan to focus on the following topics: 1. Plasma transport into the cusp. 2. Energization of ions in diamagnetic cavities. 3. Origin of waves observed in the cusp and their role in particle scattering and acceleration. 4. Interaction of FTE's with the cusp. 5. The source region of energetic ions and electrons observed in the cusp. 6. Ionospheric signatures of such processes such as Poleward Moving Auroral Forms It is the ultimate goal of the workshop to enhance our understanding of the cusp physics, its coupling to other parts of the system such as the bow shock, magnetopause and the ionosphere and the important role it plays in dayside transport and energization. Observational and theoretical contributions to this session are hereby solicited. Those interested in these topics are invited to attend and contribute through showing a few slides and/or participation in the discussions. Information regarding hotel reservations and travel arrangements will be posted on the GEM website (http://www.cpe.vt.edu/gem) in the near future. Those wishing to give a presentation or with questions regarding the workshop should contact the conveners trattner@mail.spasci.com, omidi@solanasci.com or david.g.sibeck@nasa.gov. +-------------------------------------------------------------------------+ |To subscribe GEM Messengers, send an e-mail to | | with the following command in the body of your e-mail message: | | subscribe gem | |To remove yourself from the mailing list, the command is: | | unsubscribe gem | | | |To broadcast a message to the GEM community, please contact Peter Chi at | | | |Please use plain text as the format of your submission. | | | |URL of GEM Home Page: http://aten.igpp.ucla.edu/GemWiki | |Workshop Information: http://www.cpe.vt.edu/gem/index.html | +-------------------------------------------------------------------------+
