Spectrometry of Captured Highly Charged Ions Produced Following Antiproton Annihilations

F. P. Gustafsson, M. Volponi, J. Zielinski +61

We report a proof-of-principle study demonstrating the first capture and time-of-flight spectrometry of highly charged ions (HCIs) produced following antiproton annihilations in a…

Real-time antiproton annihilation vertexing with sub-micron resolution

M. Berghold, D. Orsucci, F. Guatieri +63

The primary goal of the AEgIS experiment is to precisely measure the free fall of antihydrogen within Earth's gravitational field. To this end, a cold ~50K antihydrogen beam has to…

Synthesis of cold and trappable fully stripped HCI's via antiproton-induced nuclear fragmentation in traps

G. Kornakov, G. Cerchiari, J. Zieliński +3

The study of radioisotopes as well as of highly charged ions is a very active and dynamic field. In both cases, the most sensitive probes involve species trapped in Penning or Paul…

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…

Ultracold anions for high-precision antihydrogen experiments

G. Cerchiari, A. Kellerbauer, M. S. Safronova +2

Experiments with antihydrogen () for a study of matter--antimatter symmetry and antimatter gravity require ultracold to reach ultimate pr…

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…
