Scientific paper

We have begun a series of laboratory experiments using the combined Helicon-Cathode (HelCat) plasma facility, and the Plasma Bubble Experiment (PBeX). These devices can generate CME like structures injected into a background plasma medium. The goal of this research is to substantiate, through a series of basic plasma experiments and corroborative numerical modeling, the fundamental physics of coronal mass ejection (CME) interaction with the solar wind flow in the Sun's outer corona. Results of these laboratory experiments will be compared with the University of Michigan state-of-the-art 3D BATS-R-US MHD numerical code, which has been used to perform simulations of the propagation of CMEs into a background solar wind. The results will be compared in a systematic way to validate the numerical model under controlled laboratory settings, allowing it to be applied with greater confidence to a more realistic but less well-understood solar setting. Initial laboratory simulation results will be presented.
