Low-Energy Negative Ion Injection Beamline for Experiments with Antiprotonic Atoms at AEgIS / Rodin, Volodymyr (U. Liverpool (main) ; Cockcroft Inst. Accel. Sci. Tech.) ; Cerchiari, Giovanni (Innsbruck U.) ; Doser, Michael (CERN) ; Farricker, Aaron (U. Liverpool (main)) ; Khatri, Ghanshyambhai (CERN) ; Kornakov, Georgy (Warsaw U. of Tech. (main)) ; Welsch, Carsten (U. Liverpool (main) ; Cockcroft Inst. Accel. Sci. Tech.)
Interaction of low-energy antiprotons with nuclear targets provided fundamental knowledge about proton and neutron densities of many nuclei through the capture process, cascade on lower electron orbits, and annihilation with the nucleon. The expelled electrons produce X-rays and with the recoil particles after annihilation, thus, a sufficient amount of information can be obtained about this interaction. [...]

Monte-Carlo simulation of positronium laser excitation and anti-hydrogen formation via charge exchange / AEgIS Collaboration
The AEgIS experiment aims at producing antihydrogen (and eventually measuring the effects of the Earth gravitational field on it) with a method based on the charge exchange reaction between antiproton and Rydberg positronium. To be precise, antiprotons are delivered by the CERN Antiproton Decelerator (AD) and are trapped in a multi-ring Penning trap, while positronium is produced by a nanoporous silica target and is excited to Rydberg states by means of a two steps laser excitation. [...]

Imaging a positronium cloud in a 1 Tesla / Camper, Antoine (CERN) ; Aghion, Stefano (Milan Polytechnic ; INFN, Milan) ; Amsler, Claude (Stefan Meyer Inst. Subatomare Phys.) ; Antonello, Massimiliano (INFN, Milan ; Insubria U., Como) ; Belov, Alexander (Moscow, INR) ; Bonomi, Germano (INFM, Brescia ; INFN, Pavia) ; Brusa, Roberto (Trento U. ; TIFPA-INFN, Trento) ; Caccia, Massimo (INFN, Milan ; Insubria U., Como) ; Caravita, Ruggero (CERN) ; Castelli, Fabrizio (INFN, Milan ; Milan U.) et al.
We report on recent developments in positronium work in the frame of antihydrogen production through charge exchange in the AEgIS collaboration [1]. In particular, we present a new technique based on spatially imaging a cloud of positronium by collecting the positrons emitted by photoionization. [...]

Compression of a mixed antiproton and electron non-neutral plasma to high densities / Aghion, Stefano (Milan Polytechnic ; INFN, Milan) ; Amsler, Claude (Stefan Meyer Inst. Subatomare Phys.) ; Bonomi, Germano (Brescia U. ; INFN, Pavia) ; Brusa, Roberto S (Trento U. ; INFN, Trento) ; Caccia, Massimo (INFN, Milan ; Insubria U., Como) ; Caravita, Ruggero (Genoa U. ; INFN, Genoa) ; Castelli, Fabrizio (INFN, Milan ; Milan U.) ; Cerchiari, Giovanni (Heidelberg, Max Planck Inst.) ; Comparat, Daniel (LAC, Orsay) ; Consolati, Giovanni (Milan Polytechnic ; INFN, Milan) et al.
We describe a multi-step “rotating wall” compression of a mixed cold antiproton–electron non-neutral plasma in a 4.46 T Penning–Malmberg trap developed in the context of the AEḡIS experiment at CERN. Such traps are routinely used for the preparation of cold antiprotons suitable for antihydrogen production. [...]

AEgIS experiment: Towards antihydrogen beam production for antimatter gravity measurements / Mariazzi, Sebastiano (Stefan Meyer Inst. Subatomare Phys.) ; Aghion, Stefano (INFN, Milan ; Milan Polytechnic) ; Amsler, Claude (Bern U., LHEP) ; Ariga, Akitaka (Bern U., LHEP) ; Ariga, Tomoko (Bern U., LHEP) ; Belov, Alexandre S (Moscow, INR) ; Bonomi, Germano (INFN, Pavia ; INFM, Brescia) ; Bräunig, Philippe (Kirchhoff Inst. Phys.) ; Brusa, Roberto S (Trento U. ; INFN, Trento) ; Bremer, Johan (CERN) et al.
AEgIS (Antimatter Experiment: Gravity, Interferometry, Spectroscopy) is an experiment that aims to perform the first direct measurement of the gravitational acceleration g of antihydrogen in the Earth’s field. A cold antihydrogen beam will be produced by charge exchange reaction between cold antiprotons and positronium excited in Rydberg states. [...]
