CMS collaboration


The Compact Muon Solenoid (CMS) collaboration has successfully tested
the world's largest superconducting magnet at CERN in Geneva,
Switzerland. After the tests, the magnet was brought to full field on
September 4, 2006.

Weighing 12,500 tonnes, the CMS experiment's magnet has a 6-meter diameter, 13-meter long superconducting solenoid coil, with a magnetic field of 4 Tesla, some 100,000 times higher than that of the Earth, that stores 2.5 Giga Joules of energy, sufficient to melt 18 tons of gold. The magnet is one of the main components of the CMS detector, which is being built to study physics at the new Large Hadron Collider (LHC) at CERN.

The School of Physics and Astronomy Professor Roger Rusack, leads a
16-person group of researchers at the University of Minnesota who are
members of the CMS Collaboration. The purpose of the experiment is to search for new physical phenomena at 14 TeV (Tera-Electron Volts) which will be the highest ever man-made energy when the LHC starts operation next year.

More information about the CMS magnet, including video footage of the
test as well as an extensive profile of University of Minnesota Ph.D
student, Abraham De Benedetti, can be found in the September issue of CMS Times, linked below.
