The Laboratory for Superconducting Magnet Research (LEAS) offers its expertise in magnetic fields to IRFU physicists and is staffed by eight technicians, 17 engineers and one PhD student as of December 2012. The laboratory teams are responsible for the design and project management of superconducting magnets for experimental facilities, especially large magnets or those with high magnetic fields.
In the design of superconducting magnets, LEAS applies its expertise to the optimization of coil geometry, conductor design, mechanical, electromagnetic, and thermal calculations, and magnetic protection in the event of quench. In addition to designing magnets, LEAS has the capacity to manage large projects, to develop magnets and integrate them into cryostats, and to provide monitoring for industrial projects. The magnets are inspected jointly with the Cryogenics Laboratory and Test Station (LCSE). Measurement work includes analyses of tests at ambient and cryogenic temperatures, including quench analyses and magnetic measurements.
The R&D work carried out is partly in response to the requirements of construction projects such as the GLAD dipole in the R3B spectrometer and the ISEULT imager. Also, in view of the future development of the LHC, development work is being carried out on the use of niobium tin (Nb3Sn) and high critical temperature superconductors. The use of magnesium diboride (MgB2) conductors is also being studied.
