Query: Engineering Study of Sector Magnet for the Daedalus Experiment   The Daedalus experiment seeks to evaluate neutrino scattering effects that go
beyond the standard model. Modular accelerators are employed to produce 800 MeV
proton beams at the megawatt power level directed toward a target, producing
neutrinos. The Superconducting Ring Cyclotron (SRC) consists of identical
sectors (currently 6) of superconducting dipole magnets with iron return
frames. The Daedalus Collaboration has produced a conceptual design for the
magnet, which, after several iterations, is the current best design that
achieves the physics requirements of the experiment. The Technology and
Engineering Division (T&ED) of the MIT Plasma Science and Fusion Center was
awarded with a contract by the Daedalus team to further develop the magnet
conceptual design. The resulting Engineering Study is reported here.
