A cryogenic tracking detector for antihydrogen detection in the AEgIS experiment
C. Amsler, M. Antonello, A. Belov +55
We present the commissioning of the Fast Annihilation Cryogenic Tracker detector (FACT), installed around the antihydrogen production trap inside the 1 T superconducting magnet of…
Rydberg-positronium velocity and self-ionization studies in 1T magnetic field and cryogenic environment
M. Antonello, A. Belov, G. Bonomi R. S. Brusa +43
We characterized the pulsed Rydberg-positronium production inside the AEgIS (Antimatter Experiment: Gravity, Interferometry, Spectroscopy) apparatus in view of antihydrogen formati…
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…
Velocity selected production of metastable positronium
C. Amsler, M. Antonello, A. Belov +52
Positronium in the metastable state exhibits a low electrical polarizability and a long lifetime (1140 ns) making it a promising candidate for interferometry experiments wit…
Producing long-lived Ps via laser excitation in magnetic and electric fields
S. Aghion, C. Amsler, M. Antonello +62
Producing positronium (Ps) in the metastable state is of interest for various applications in fundamental physics. We report here about an experiment in which Ps atom…
Measurement of antiproton annihilation on Cu, Ag and Au with emulsion films
S. Aghion, C. Amsler, A. Ariga +69
The characteristics of low energy antiproton annihilations on nuclei (e.g. hadronization and product multiplicities) are not well known, and Monte Carlo simulation packages that us…
Laser Cooling of Molecular Anions
Pauline Yzombard, Mehdi Hamamda, Sebastian Gerber +2
We propose a scheme for laser cooling of negatively charged molecules. We briefly summarise the requirements for such laser cooling and we identify a number of potential candidates…
Probing surface electric field noise with a single ion
N. Daniilidis, S. Gerber, G. Bolloten +5
We report room-temperature electric field noise measurements combined with in-situ surface characterization and cleaning of a microfabricated ion trap. We used a single-ion electri…
