Title: Hybrid Conformal Solenoid: how to suppress screening currents to enable 50 T for Spectroscopy, Muon Cooling, and Plasma Heating in Tokamaks
Series: MS&T Sciences Seminar
Abstract: Screening currents strongly limit the performance of solenoids as one pushes beyond ~30 T. A 50 T hybrid conformal solenoid is being developed in which screening currents are strongly suppressed by end windings that utilize Bi-2212 superconductor. A novel structure is proposed that provides stress management at the wire level within the end windings.
The hybrid conformal solenoid has three significant applications: a series-connected superconducting spectrometer to extend to 50 T the experimental programs at NHMFL; fast muon cooling for a >TeV muon collider, for which hundreds of 50 T solenoidal lenses are needed to fast-cool the muon beams; and a fast-ramping 30 T central solenoid to inductively heat the plasma in a tokamak.
