  • [hal-01582802] Calorimeter development for the SuperNEMO double beta decay experiment

    28 novembre 2017, par A.S. Barabash, A. Basharina-Freshville, S. Blot, M. Bongrand, Ch. Bourgeois
    SuperNEMO is a double- β decay experiment, which will employ the successful tracker–calorimeter technique used in the recently completed NEMO-3 experiment. SuperNEMO will implement 100 kg of double- β decay isotope, reaching a sensitivity to the neutrinoless double- β decay ( 0νββ ) half-life of the (...)
  • [hal-01645814] Anisotropic two-body dissociation by highly charged ion impact

    28 novembre 2017, par Jyoti Rajput, A. Agnihotri, A. Cassimi, X. Fléchard, S. Guillous
    The angular distribution of fragment emission with respect to the incoming beam direction is measured. In case of two body breakup of di-cationic molecular ions, such as D2O 2+ and C2H 2+ 2 , a strong anisotropy is observed when one of the fragments is an H+ or D+. These molecular ions were (...)
  • [hal-01645919] Search for Axionlike Dark Matter through Nuclear Spin Precession in Electric and Magnetic Fields

    28 novembre 2017, par C. Abel, N.J. Ayres, G. Ban, G. Bison, K. Bodek
    We report on a search for ultra-low-mass axion-like dark matter by analysing the ratio of the spin-precession frequencies of stored ultracold neutrons and $^199$Hg atoms for an axion-induced oscillating electric dipole moment of the neutron and an axion-wind spin-precession effect. No signal (...)
  • [hal-01645779] Active compensation of magnetic field distortions based on vector spherical harmonics field description

    28 novembre 2017, par G. Wyszyński, K. Bodek, S. Afach, G. Bison, Z. Chowdhuri
    An analytic solution to the magnetostatic inverse problem in the framework of vector spherical harmonic basis functions is presented. This formalism is used for the design of a spherical magnetic field compensation system and its performance is compared with an already existing rectangular coil (...)
  • [hal-01642862] Highly stable atomic vector magnetometer based on free spin precession

    22 novembre 2017, par S. Afach, G. Ban, G. Bison, K. Bodek, Z. Chowdhuri
    We present a magnetometer based on optically pumped Cs atoms that measures the magnitude and direction of a 1 $\mu$T magnetic field. Multiple circularly polarized laser beams were used to probe the free spin precession of the Cs atoms. The design was optimized for long-time stability and (...)
