Description
The muEDM Collaboration is searching for the muon EDM by implementing, for the first time, the frozen-spin technique [Farley et al. (2004), PRL:93:052001]. A factor 1000 improvement upon the current limit $d_\mu<1.8\times10^{-19}\,e\mathrm{cm}\,\,(95\%\,\,\mathrm{C.L.})$ [Bennett et al. (2009), PRD:80:052008] is expected from this approach. A sub-microsecond trapping scheme is being developed to store $28\,\mathrm{MeV}/c$ muons on a circular orbit exposed to a $0.3\,\mathrm{MV/m}$ radial electric field inside a $3\,\mathrm{T}$ solenoid. A pulsed magnetic field will accordingly kick the longitudinal momentum of injected muons, thereafter axially confined by a static weakly-focusing magnetic field. Prototypes are being tested to explore different field geometries and study the effect of eddy currents on the frozen-spin conditions.
