Room-temperature emission of muonium from aerogel and zeolite targets
A. Antognini, P. Crivelli, L. Gerchow +12
A low-emittance, high-intensity atomic beam of muonium () using superfluid helium as muon-to-muonium converter is being developed at the Paul Scherre…
Intense beam of metastable Muonium
G. Janka, B. Ohayon, Z. Burkley +10
Precision spectroscopy of the Muonium Lamb shift and fine structure requires a robust source of 2S Muonium. To date, the beam-foil technique is the only demonstrated method for cre…
New bounds from positronium decays on massless mirror dark photons
C. Vigo, L. Gerchow, B. Radics +3
We present the results of a search for a hidden mirror sector in positronium decays with a sensitivity comparable with the bounds set by the prediction of the primordial He a…
A new approach for the ortho-positronium lifetime determination in a vacuum cavity
C. Vigo, M. Raajimakers, L. Gerchow +3
Currently, the experimental uncertainty for the determination of the ortho-positronium (o-Ps) decay rate is at 150 ppm precision; this is two orders of magnitude lower than the the…
First search for invisible decays of ortho-positronium confined in a vacuum cavity
C. Vigo, L. Gerchow, L. Liszkay +2
The experimental setup and results of the first search for invisible decays of ortho-positronium (o-Ps) confined in a vacuum cavity are reported. No evidence of invisible decays at…
High efficiency cyclotron trap assisted positron moderator
L. Gerchow, D. A. Cooke, S. Braccini +8
We report the realisation of a cyclotron trap assisted positron tungsten moderator for the conversion of positrons with a broad keV- few MeV energy spectrum to a mono-energetic eV…
