WP3: IR Magnets

WP3: IR Magnets

WP3 is in charge of the design, engineering and construction of short models, prototypes and the series magnets, including spares, of the Insertion Region (IR) magnets. This includes the Nb3Sn triplet, separation and recombination dipoles, dipolar and higher order correctors. The mandate also concerns magnet assembly in cold masses, cold mass assembly in cryostats, power test and magnetic measurements.

WP3 develops novel technologies for the Nb3Sn triplet, with the longest Nb3Sn magnet (7 m) and the first to be installed using a structure based on Al shells and bladder and key. It is also the first accelerator magnet to be protected via CLIQ, a system invented at CERN. Furthermore, a double collaring structure to be used for the nested corrector will be a first in accelerator magnets. A second type of dipole corrector shall be based on canted cos theta design, another first for accelerator magnets at CERN.

WP3 works hand in hand with several other work packages and will actively collaborate to the WP16 (HL IT String Test) and to the relative data analysis. WP3 is also technically responsible for the interconnection of the magnets and the definition of the field model.
