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…
AEgIS Experiment at CERN: Design and Commissioning of SARA (Scintillator Assemblies to Reveal Annihilations)
P. Conte, G. Consolati, M. Prata +12
SARA is the system of plastic scintillators coupled with silicon photomultipliers that will take part in the AEgIS experiment at CERN, measuring the time-of-flight of antihydrogen…
High-efficiency position resolved gamma ray detectors for 2D-measurements of the angular correlation of annihilation radiation
Kilian Brenner, Francesco Guatieri, Christoph Hugenschmidt
The measurement of the 2D-Angular Correlation of Electron Positron Annihilation Radiation (ACAR) provides unique information about the bulk electronic structure of single crystals.…
TALOS (Total Automation of LabVIEW Operations for Science): A framework for autonomous control systems for complex experiments
M. Volponi, J. Zieliński, T. Rauschendorfer +52
Modern physics experiments are frequently very complex, relying on multiple simultaneous events to happen in order to obtain the desired result. The experiment control system plays…
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…
Spatially-resolved charge detectors for particle beam optimization with femtoampere resolution achieved by in-vacuum signal preamplification
Kilian Brenner, Michael Zimmermann, Maik Butterling +3
We present the design of a Faraday cup-like charged particle detector in a four quadrant configuration aimed at facilitating the alignment of low-intensity beams of exotic particle…
Integrated anti-electronics for positron annihilation spectroscopy
Francesco Guatieri
Imaging the features of a sample using Positron Annihilation Spectroscopy (PAS) is currently achieved by rastering, i.e. by scanning the sample surface with a sharply focused posit…
Positronium laser cooling via the - transition with a broadband laser pulse
L. T. Glöggler, N. Gusakova, B. Rienäcker +49
We report on laser cooling of a large fraction of positronium (Ps) in free-flight by strongly saturating the - transition with a broadband, long-pulsed 243 nm alexandri…
Imaging low-energy positron beams in real-time with unprecedented resolution
Michael Berghold, Vassily Vadimovitch Burwitz, Lucian Mathes +2
Particle beams focused to micrometer-sized spots play a crucial role in forefront research using low-energy positrons. Their expedient and wide application, however, requires highl…

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…
