Optimizing Antihydrogen Production via Slow Plasma Merging
E D Hunter, M Bumbar, C Amsler +29
We measure the time-dependent temperature and density distribution of antiprotons and positrons while slowly combining them to make antihydrogen atoms in a nested Penning-Malmberg…
Precision Test of Bound-State QED at Intermediate-Z with Kaonic Neon
S. Manti, F. Sgaramella, L. Abbene +40
We report Dirac-Fock calculations of transition energies for kaonic neon (KNe). For the most intense line, the 7-6 transition, the calculated energy is 9450.28 eV, which includes a…
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…
Measurement of the Principal Quantum Number Distribution in a Beam of Antihydrogen Atoms
B. Kolbinger, C. Amsler, S. Arguedas Cuendis +35
The ASACUSA (Atomic Spectroscopy And Collisions Using Slow Antiprotons) collaboration plans to measure the ground-state hyperfine splitting of antihydrogen in a beam at the CERN An…
A hydrogen beam to characterize the ASACUSA antihydrogen hyperfine spectrometer
C. Malbrunot, M. Diermaier, M. C. Simon +19
The antihydrogen programme of the ASACUSA collaboration at the antiproton decelerator of CERN focuses on Rabi-type measurements of the ground-state hyperfine splitting of antihydro…
Hyperfine spectroscopy of hydrogen and antihydrogen in ASACUSA
E. Widmann, C. Amsler, S. Arguedas Cuendis +31
The ASACUSA collaboration at the Antiproton Decelerator of CERN aims at a precise measurement of the antihydrogen ground-state hyperfine structure as a test of the fundamental CPT…
