Luvata Success in Cern
CERN Press Release on September 4, 2006:
Mammoth Compact Muon Solenoid (CMS) magnet reaches full-field at CERN
Geneva, 4 September 2006. The world ’s largest superconducting solenoid magnet has reached full field. Weighing in at 12,500 tonnes, the CMS experiment’s magnet is built around a 6-metre diameter, 13-metre long superconducting solenoid coil. It generates a field of 4 tesla, some 100,000 times higher than that of the Earth, and stores 2.5 Giga Joules of energy, sufficient to melt 18 tonnes of gold.”
The CMS is one of the four big experiments in the Large Hadron Collider (LHC) under construction at Cern. On Tuesday the 22 of August 2006 at 11:00 the superconducting coil of the CMS was charged with a current exceeding 19 kA, which meant that the superconducting (SC) coil reached its nominal field of 4 tesla. The cylindrical detector is 21 meter long and 16 meter in diameter.
Luvata Pori Oy Superconductors was the sole supplier being able to manufacture the wire needed for this detector. The project was to deliver between the years 2000 and 2002 19 tons of SC NbTi wire, the commercial value being 3.8 million €. This was a project where quality and delivery on time was crucial. Cern recognized the effort by Luvata Pori Oy Superconductors in the year of 2002 by giving the awards “Crystal Award” and the “CMS Gold Award of the Year 2002”.
