LARP Long ${\rm Nb}_{3}{\rm Sn}$ Racetrack Coil Program

Development of high-performance Nb3Sn quadrupoles is one of the major goals of the LHC Accelerator Research Program (LARP). As part of this program, long racetrack magnets are being made in order to check that the change in coil length that takes place during reaction is correctly accounted for in the quadrupole design and to check for length effects in implementing the "shell" method of coil supp...
