Cyclotron cooling to cryogenic temperature in a Penning-Malmberg trap with a large solid angle acceptance
C. Amsler, H. Breuker, S. Chesnevskaya +35
Magnetized nonneutral plasma composed of electrons or positrons couples to the local microwave environment via cyclotron radiation. The equilibrium plasma temperature depends on th…
Constraints on the Coupling between Axionlike Dark Matter and Photons Using an Antiproton Superconducting Tuned Detection Circuit in a Cryogenic Penning Trap
Jack A. Devlin, Matthias J. Borchert, Stefan Erlewein +17
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…
Direct limits on the interaction of antiprotons with axion-like dark matter
C. Smorra, Y. V. Stadnik, P. E. Blessing +18
Astrophysical observations indicate that there is roughly five times more dark matter in the Universe than ordinary baryonic matter, with an even larger amount of the Universe's en…
Antihydrogen level population evolution: impact of positron plasma length
B. Radics, Y. Yamazaki
Antihydrogen is produced by mixing an antiproton and a positron plasma in a cryogenic electromagnetic trap. The dominant antihydrogen formation mechanism is three-body recombinatio…
Scaling behaviour of the ground-state antihydrogen yield from CTMC simulation as a function of positron density and temperature
B. Radics, D. J. Murtagh, Y. Yamazaki +1
Antihydrogen production has reached such a level that precision spectroscopic measurements of its properties are within reach. In particular, the ground-state level population is o…
Measurement of ultra-low heating rates of a single antiproton in a cryogenic Penning trap
M. J. Borchert, P. E. Blessing, J. A. Devlin +15
We report on the first detailed study of motional heating in a cryogenic Penning trap using a single antiproton. Employing the continuous Stern-Gerlach effect we observe cyclotron…
