Record at 31 T in 50 mm

A new magnet using a radially cooled helix in its center has been operated end November 2013 at 31 T in a 50 mm room temperature bore. The power required for this new magnet at 31T is equal to what was needed at 30.2 T for the previous model.
This progress has been obtained thanks to the use of the radially cooled techique that leads to a better cooling efficiency and a stronger filling factor. 

It corresponds to a saving of 4% of electricity for a given magnetic field. This magnetic field configuration will be offered to the user community starting from April 2014.
A 34 mm room temperature bore version is under development.
