The Center for
Magnetic Self-Organization in Laboratory and Astrophysical Plasmas
(CMSO) is a Physics Frontier Center established
by the National Science Foundation. Its aim is to investigate
basic problems in plasma physics, common to the laboratory and
cosmos. Magnetic self-organization refers to the tendency of
plasmas to rearrange spontaneously through processes that involve
changing magnetic fields. Six phenomena form the focus for the
Center, all of which can occur as part of the process of magnetic
self-organization: dynamo, magnetic reconnection, angular momentum
transport, ion heating, magnetic chaos and transport, and magnetic
helicity conservation and transport.
The Center brings together
laboratory and astrophysical scientists (as well as experimentalists,
theorists, and computational scientists) to work together on
the common problems. Five experiments are enlisted for this
purpose: the Madison
Symmetric Torus (MST) reversed field pinch at the University
of Wisconsin-Madison, the Magnetic
Reconnection Experiment (MRX) and the Magnetorotational
Instability Experiment (MRI), both at the Princeton Plasma Physics
Laboratory, the the Swarthmore
Spheromak Experiment (SSX) at Swarthmore
College and the Sustained
Spheromak Physics Experiment (SSPX) at
the Lawrence Livermore National Laboratory. This set of experiments
displays particularly robust magnetic self-organization, and
will permit joint investigations of a phenomenon over a range
of physical parameters. Computational tools include two large-scale
fluid codes: the FLASH
code (the University of Chicago) written originally for astrophysical
application and the NIMROD
code (developed by researchers at many institutions, and sponsored
by the US Department of Energy) written for laboratory application.
Computation, plus analytic theory, is employed to connect experimental
results to theory and astrophysics, as well as to examine new
physical mechanisms. Collaborations are also being established
with other institutions.
Set up with a funding
authorization of five years, the Center was initiated in September,
2003. Much of the established infrastructure-experimental
and computational is maintained by the Department of Energy.
Hence, the Center can be viewed as a partnership between the
NSF and DOE.
