Record accumulation of antiprotons in a Penning-Malmberg Trap and their preparation for improved production of antihydrogen beams
B. Lee, B. Kim, P. Adrich +35
CERN's AD/ELENA ``antimatter factory'' - unique worldwide - serves several experiments, all of which use electromagnetic traps to accumulate antiprotons for fundamental science. Th…
Cryogenic source of atomic tritium for neutrino-mass measurements and precision spectroscopy
Aleksei Semakin, Janne Ahokas, Tom Kiilerich +9
We propose a concept for a cryogenic source of atomic tritium at sub-Kelvin temperatures and energies suitable for magnetic trapping. The source is based on the dissociation of sol…
Gravitational and other shifts of whispering gallery and gravitational state interference patterns of light neutral particles
V. V. Nesvizhevsky, J. A. Pioquinto, K. Schreiner +7
We discuss small shifts in the interference patterns of gravitational and whispering gallery quantum states that can be observed with neutrons, atoms, antiatoms, muonium, positroni…
Towards Precision Spectroscopy of Antiprotonic Atoms for Probing Strong-field QED
Gonçalo Baptista, Shikha Rathi, Michael Roosa +26
PAX (antiProtonic Atom X-ray spectroscopy) is a new experiment with the aim to test strong-field quantum electrodynamics (QED) effects by performing high-precision x-ray spectrosco…
GRASIAN: Shaping and characterization of the cold hydrogen and deuterium beams for the forthcoming first demonstration of gravitational quantum states of atoms
Carina Killian, Philipp Blumer, Paolo Crivelli +9
A low energy particle confined by a horizontal reflective surface and gravity settles in gravitationally bound quantum states. These gravitational quantum states (GQS) were so far…
