Upgrade of the positron system of the ASACUSA-Cusp experiment
A. Lanz, C. Amsler, H. Breuker +35
The ASACUSA-Cusp collaboration has recently upgraded the positron system to improve the production of antihydrogen. Previously, the experiment suffered from contamination of the va…
Slow positron production and storage for the ASACUSA-Cusp experiment
D. J. Murtagh, C. Amsler, H. Breuker +35
The ASACUSA Cusp experiment requires the production of dense positron plasmas with a high repetition rate to produce a beam of antihydrogen. In this work, details of the positron p…
SDR, EVC, and SDREVC: Limitations and Extensions
E. D. Hunter, C. Amsler, H. Breuker +34
Methods for reducing the radius, temperature, and space charge of nonneutral plasma are usually reported for conditions which approximate an ideal Penning Malmberg trap. Here we sh…
GRASIAN: Towards the first demonstration of gravitational quantum states of atoms with a cryogenic hydrogen beam
Carina Killian, Zakary Burkley, Philipp Blumer +12
At very low energies, a light neutral particle above a horizontal surface can experience quantum reflection. The quantum reflection holds the particle against gravity and leads to…
A Rydberg hydrogen beam for studies of stimulated deexcitation
Tim Wolz, Maxime Allemand, Daniel Comparat +7
We present a Rydberg hydrogen beamline developed to commission techniques of stimulated deexcitation for application in antihydrogen experiments at CERN's Antiproton Decelerator. T…
Charge radii of exotic potassium isotopes challenge nuclear theory and the magic character of
Á. Koszorús, X. F. Yang, W. G. Jiang +26
Nuclear charge radii are sensitive probes of different aspects of the nucleon-nucleon interaction and the bulk properties of nuclear matter; thus, they provide a stringent test and…
Laser spectroscopy of indium Rydberg atom bunches by electric field ionization
A. R. Vernon, C. M. Ricketts, J. Billowes +11
This work reports on the application of a novel electric field-ionization setup for high-resolution laser spectroscopy measurements on bunched fast atomic beams in a collinear geom…
Magnetic moments of short-lived nuclei with part-per-million accuracy: Towards novel applications of -detected NMR in physics, chemistry and biology
R. D. Harding, S. Pallada, J. Croese +24
We determine for the first time the magnetic dipole moment of a short-lived nucleus with part-per-million (ppm) accuracy. To achieve this two orders of magnitude improvement over p…
