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…
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…
In-beam hyperfine spectroscopy of antihydrogen, hydrogen and deuterium
E. Widmann
The ASACUSA collaboration is developing a polarized beam of antihydrogen atoms to precisely determine the ground-state hyperfine structure for studies of CPT and Lorentz invariance…
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…
A large octupole magnetic trap for research with atomic hydrogen
J. Ahokas, A. Semakin, J. Järvinen +12
We describe the design and performance of a large magnetic trap for storing and cooling of atomic hydrogen (H). The trap operates in the vacuum space of a dilution refrigerator at…
Efficient positronium production by stimulated decay from the level
M. Antonello, A. Belov, G. Bonomi +48
We investigate experimentally the possibility of enhancing the production of positronium atoms by driving the - and - transitions, overcoming the nat…
