We constrain the coupling between axionlike particles (ALPs) and photons, measured with the superconducting resonant detection circuit of a cryogenic Penning trap. By searching the noise spectrum of our fixed-frequency resonant circuit for peaks caused by dark matter ALPs converting into photons in the strong magnetic field of the Penning-trap magnet, we are able to constrain the coupling of ALPs with masses around $2.7906-2.7914\,\textrm{neV/c}^2$ to $g_{a\gamma}< 1 \times 10^{-11}\,\textrm{GeV}^{-1}$.

Superconducting solenoid system with adjustable shielding factor for precision measurements of the properties of the antiproton / Devlin, Jack A (RIKEN (main) ; CERN) ; Wursten, Elise (RIKEN (main) ; CERN) ; Harrington, James A (RIKEN (main) ; Heidelberg, Max Planck Inst.) ; Higuchi, Takashi (RIKEN (main) ; U. Tokyo (main)) ; Blessing, Pascal E (RIKEN (main) ; Darmstadt, GSI) ; Borchert, Matthias J (RIKEN (main) ; Leibniz U., Hannover) ; Erlewein, Stefan (RIKEN (main) ; CERN ; Heidelberg, Max Planck Inst.) ; Hansen, Jannek J (RIKEN (main)) ; Morgner, Jonathan (RIKEN (main) ; Leibniz U., Hannover) ; Bohman, Matthew A (RIKEN (main) ; Heidelberg, Max Planck Inst.) et al.
A superconducting self-shielding three-solenoid system with an adjustable shielding factor is developed, implemented, and characterized using a single antiproton in a Penning trap. With the tuned system, we suppress external magnetic field disturbances by up to a factor of 225 ± 15, allowing antiproton-to-proton charge-to-mass ratio comparisons with fourfold reduced frequency fluctuations and antiproton magnetic moment determinations with tenfold reduced uncertainty..
