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…
Toward inertial sensing with a monochromatic positronium beam
Sebastiano Mariazzi, Ruggero Caravita, Michael Doser +2
In this work, we discuss the possibility of inertial sensing with positronium in the metastable state for the measurement of optical dipole, relativistic and gravitational…
A fiber detector to monitor ortho-Ps formation and decay
Benjamin Rienäcker, Roberto Sennen Brusa, Ruggero Caravita +4
We describe a novel method to use a scintillating fiber detector similar to the Fast Annihilation Cryogenic Tracking (FACT) used at the antimatter experiment AEgIS to monitor the p…
Absolute fraction of emitted Ps determined by GEANT4 supported analysis of gamma spectra
Benjamin Rienäcker, Thomas Gigl, Giancarlo Nebbia +2
The fraction of positronium (Ps) emitted from a surface of a germanium single crystal at high temperature is usually assumed to approach unity at zero positron implantation energy.…
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…
