Optically Pumped Cs Magnetometers Enabling a High-Sensitivity Search for the Neutron Electric Dipole Moment
C. Abel, S. Afach, N. J. Ayres +57
An array of sixteen laser-pumped scalar Cs magnetometers was part of the neutron electric dipole moment (nEDM) experiment taking data at the Paul Scherrer Institute in 2015 and 201…
Searching for axion stars and Q-balls with a terrestrial magnetometer network
D. F. Jackson Kimball, D. Budker, J. Eby +6
Light (pseudo-)scalar fields are promising candidates to be the dark matter in the Universe. Under certain initial conditions in the early Universe and/or with certain types of sel…
M(H) dependence and size distribution of SPIONs measured by atomic magnetometry
Simone Colombo, Victor Lebedev, Zoran D. Grujic +2
We demonstrate that the quasistatic recording of the magnetic excitation function M(H) of superparamagnetic iron oxide magnetic nanoparticle (SPION) suspensions by an atomic magnet…
Design and performance of an absolute He/Cs magnetometer
H. -C. Koch, G. Bison, Z. D. Grujić +8
We report on the design and performance of a highly sensitive combined He/Cs magnetometer for the absolute measurement of magnetic fields. The magnetometer relies on the magnet…
Imaging magnetic scalar potentials by laser-induced fluorescence from bright and dark atoms
Ilja Fescenko, Antoine Weis
We present a spectroscopic method for mapping two-dimensional distributions of magnetic field strengths (magnetic scalar potential lines) using CCD recordings of the fluorescence p…
Measurement of the scalar third-order electric polarizability of the Cs ground state using CPT-spectroscopy in Ramsey geometry
Jean-Luc Robyr, Paul Knowles, Antoine Weis
The AC Stark shift induced by blackbody radiation is a major source of systematic uncertainty in present-day cesium microwave frequency standards. The shift is parametrized in term…
A high-sensitivity push-pull magnetometer
E. Breschi, Z. D. Grujic, P. Knowles +1
We describe our approach to atomic magnetometry based on the push-pull optical pumping technique. Cesium vapor is pumped and probed by a resonant laser beam whose circular polariza…
A large sample study of spin relaxation and magnetometric sensitivity of paraffin-coated Cs vapor cells
N. Castagna, G. Bison, G. Di Domenico +5
We have manufactured more than 250 nominally identical paraffin-coated Cs vapor cells (30 mm diameter bulbs) for multi-channel atomic magnetometer applications. We describe our ded…
Dependence of Resonant Absorption Linewidth on Atomic Vapour Column Thickness for D1 Line of Cs Atoms Confined in Nano-Cell
A. Sargsyan, D. Sarkisyan, Y. Pashayan-Leroy +3
A new nano-cell with smoothly varying longitudinal thickness of the atomic vapour layer L in the range of 350 - 5100 nm allowing to study the resonant absorption of D1 and D2 lines…
Sensitivity of double resonance alignment magnetometers
G. Di Domenico, H. Saudan, G. Bison +2
We present an experimental study of the intrinsic magnetometric sensitivity of an optical/rf-frequency double resonance magnetometer in which linearly polarized laser light is used…
Reconciliation of experimental and theoretical electric tensor polarizabilities of the cesium ground state
S. Ulzega, A. Hofer, P. Moroshkin +1
We present a new theoretical analysis of the strongly suppressed F- and M-dependent Stark shifts of the Cs ground state hyperfine structure. Our treatment uses third order perturba…
