An experimental search for an electric dipole moment (EDM) of the neutron has been carried out at the Institut Laue-Langevin, Grenoble. Spurious signals from magnetic-field fluctuations were reduced to insignificance by the use of a cohabiting atomic-mercury magnetometer. Systematic uncertainties, including geometric-phase-induced false EDMs, have been carefully studied. The results may be inte...
This paper presents a framework of data-driven intelligence system which can be applied on magnetic field-assisted electrical discharge machining (MF-EDM) process for SiC particulate reinforced Al-based metal matrix composites (SiCp/Al) with different high-volume fractions. The implemented consists data modelling, predicating, optimization and monitoring modules. A multi-objective moths search ...
We calculate the Zeeman frequency shifts due to interactions with the light in a far-off-resonance optical dipole trap. These shifts are important for potential use of such a trap to search for an atomic permanent electric-dipole moment ~EDM!. We present numerical results for Cs and Hg, as examples of paramagnetic and diamagnetic atoms. The vector and tensor light shifts are calculated for a la...
In the present paper influence of tensor electric and magnetic polarizabilities on spin evolution in the resonance deuteron EDM experiment is considered in details. It is shown that besides EDM the electric and magnetic polarizabilities also contribute to the vertical spin component P3. Moreover, the electric polarizability contributes to the P3 component even when the deuteron EDM is supposed ...
We request support to develop a proposal for a new, sensitive method of searching for an electric dipole moment (EDM) of charged particles in a magnetic storage ring. The ring design is based on forced synchrotron oscillations that accumulate an EDM signal with each oscillation. Slow extraction of the beam onto a target provides a scattered flux whose asymmetry as a function of the time during ...
Trapped ultracold neutrons (UCNs) have for many years been the mainstay of experiments to search for the electric dipole moment (EDM) of the neutron, a critical parameter in constraining scenarios of new physics beyond the Standard Model. Because their energies are so low, UCNs preferentially populate the lower region of their physical enclosure and do not sample uniformly the ambient magnetic ...
We propose an experiment to search for a permanent atomic electric-dipole moment (EDM) using laser-cooled Yb atoms launched in an atomic fountain. A uniform B field sets the quantization axis, and the Ramsey separated-oscillatory-fields method is used to measure the Zeeman precession frequency of the atoms. Laser beams of appropriate polarization are used for preparation and detection in a give...
asymmetric polyethersulfone (pes) microfiltration flat sheet membranes were composed by the phase inversion method (pim) and were used as supports. composite membranes were fabricated by coating silicone rubber as selective layer. effect of different concentrations of pes and pdms and different solvent such as nmp, dmf and dms effects as pes solvents and support thickness and different coagulat...
Yannis K. Semertzidis, BNL, October 2011 for the Storage Ring EDM Collaboration The storage ring EDM collaboration by the time of the workshop is expecting to have submitted a proposal to DOE for a proton EDM experiment sensitive to 10−29e · cm, see [1]. The method utilizes polarized protons at the, so-called “magic” momentum of 0.7 GeV/c in an all-electric storage ring. At this momentum, the p...
