2 Physics Motivation for Neutron EDM Measurement Time Reversal Violation CP Violation (in the light-quark baryon sector) Physics Beyond the Standard Model Standard Model predicts d n ~ e cm Super Symmetric Models predict d n e cm Baryon Asymmetry of universe Require CP violation beyond the SM SM Prediction Experiment e e cm e cm μ e cm e cm n e cm e cm 2
3 History of Neutron EDM Measurements Current neutron EDM upper limit: < 3.0 x e cm (90% C.L.) 3
4 Neutron EDM Experiments r r Neutron precession frequency will shift by Δ ω = 2 d E/ h (d = e cm, E = 10 KV/cm => 10-7 Hz shift ) Ramsey s Separated Oscillatory Field Method Limitations: Short duration for observing the precession Systematic error due to motional magnetic field (v x E) Both can be improved by using ultra-cold neutrons 4
5 Ultra-Cold Neutrons (UCN) First suggested by Fermi Many material provides a repulsive potential of ~ 100 nev (10-7 ev) for neutrons Ultra-cold neutrons (velocity < 8 m/s) can be stored in bottles (until they decay). Gravitational energy is ~ 10-7 ev per meter UCN can be produced with cold-moderator (tail of the Maxwell distribution) 5
6 Neutron EDM Experiment with Ultra Cold Neutrons ILL Measurement Use 199 Hg co-magnetometer to sample the variation of B-field in the UCN storage cell Limited by low UCN flux of ~ 5 UCN/cm 3 A higher UCN flux can be obtained by using the superthermal down-scattering process in superfluid He 6
7 UCN Production in Superfluid 4 He Incident cold neutron with momentum of 0.7 A -1 (10-3 ev) can excite a phonon in 4 He and become an UCN (Golub and Pendlebury) 7

12 Neutron EDM Measurement Cycle Fill cells with superfluid 4 He containing polarized 3 He Produce polarized UCNs with polarized 1mev neutron beam Flip n and 3 He spin by 90 o using a π/2 RF coil Precess UCN and 3 He in a uniform B field (~10mG) and a strong E field (~50KV/cm). (ν( 3 He) ~ 33 Hz, ν(n) ~ 30 Hz) Detect scintillation light from the reaction n + 3 He p + t 1 1 Nt () = Ne { + [1 PPcos( ω t+ φ)]} Γ tott 3 τ n r β τ3 Empty the cells and change E field direction and repeat the measurement 12

29 Summary Neutron EDM measurement addresses fundamental questions in physics (CP violation in light-quark baryons). A new neutron EDM experiment uses UCN production in superfluid helium and polarized 3 He as co-magnetometer and analyser. The goal of the proposed measurement is to improve the current neutron EDM sensitivity by two orders of magnitude. Many feasibility studies have been carried out. Construction is expected to start in FY
