The first triplet of superconducting multipoles of the S3 Super Separator Spectrometer arrived at Ganil on August 29, 2018. S3 is one of the experiment rooms of the Spiral2 facility. The magnet, with a mass of 2.8 tonnes, is 1.8 m long and almost as high. This innovative type of magnet is very compact despite the number of optical functions it can generate (quadrupole, sextupole, octupole and dipole). It is the first of a series of seven to be delivered to the Ganil.
The magnetic field is generated by a niobium-titanium alloy (NbTi) conductor arranged in an epoxy/glass fibre matrix and operate at the temperature of the liquid helium (4.2 kelvins). The power supply leads are composed of two types of high-temperature superconductors and nitrogen-cooled.
It’s a unique design resulting from a collaboration between Ganil, CEA/Irfu, the American laboratory in Argonne Nat. Lab. and the two manufacturers in charge of prototyping and series (Advanced Magnet Lab. for superconducting coils, Cryomagnetics Inc. for cryostats and integration).
This element was financed by EQUIPEX n° 10-EQPX-0046, awarded to S3 by the National Research Agency in 2011.
