Description
The ISOLDE Superconducting Recoil Separator (ISRS) at CERN [1-3] is a high-resolution spectrometer for analysing the heavy fragments produced in reactions induced by ISOLDE's exotic beams. ISRS design is based on a compact FFAG particle storage ring composed of short straight multifunction superconducting magnets able to accommodate a wide range of momentum and energy spread. The team has developed a magnet prototype MAGDEM, a very compact, low current, large aperture Nb-Ti CCT superconducting magnet with both dipole and quadrupole functions. It features an innovative cryogen-free cooling system based on GM cryocoolers and a LN2 pre-cooling system [4].
