Abstract— A future Electron Ion Collider (EIC) may require high gradient superconducting quadrupole magnets for final focusing of the hadron beam in the interaction region. Due to the closeness to the beam collision point and the narrow 25mr crossing angle these high gradient magnets will reside in close proximity to electron beam magnets, thereby requiring a very compact support structure in comparison with typical accelerator magnet support structures, for the high Lorentz forces that are generated with excitation. This paper reports on the design of a proof of principle support structure for a 132 T/m, 120mm aperture superconducting magnet, utilizing the (HQ) coil design developed for the LHC Accelerator Research Program (LARP). In addition to the design work a 15cm long mechanical model based on the design is being built and loaded to the required level of coil precompression at room temperature, and then cooled to 77K to also confirm the level of coil precompression at cryogenic conditions. Future work will include construction and testing of a proof of principle magnet based on the design in an accelerated time frame, utilizing previously tested LARP HQ coils.
