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…
First Results on the Search for Chameleons with the KWISP Detector at CAST
S. Arguedas Cuendis, J. Baier, K. Barth +50
We report on a first measurement with a sensitive opto-mechanical force sensor designed for the direct detection of coupling of real chameleons to matter. These dark energy candida…
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…
Improved Search for Solar Chameleons with a GridPix Detector at CAST
V. Anastassopoulos, S. Aune, K. Barth +66
We report on a new search for solar chameleons with the CERN Axion Solar Telescope (CAST). A GridPix detector was used to search for soft X-ray photons in the energy range from 200…
