Positron Manipulation and Positronium Laser Excitation in AEgIS / Mariazzi, Sebastiano (OAW, Vienna) ; Caravita, Ruggero ; Aghion, Stefano ; Amsler, Claude ; Ariga, Akitaka ; Ariga, Tomoko ; Bonomi, Germano ; Bräunig, Philippe ; Bremer, Johan (CERN) ; Brusa, Roberto S et al.
Production of antihydrogen by using the charge exchange reaction, as proposed by AEgIS (Antimatter Experiment: gravity, Interferometry, Spectroscopy), requires the formation of a dense cloud of positronium atoms excited to Rydberg states. In this work, the recent advances in AEgIS towards this result are described. [...]

The present status of the AEGIS experiment at CERN (AD-06), on the way of forming anti-hydrogen for a first gravity measurement, is reviewed. Recent results in trapping and cooling positrons and antiprotons in the main electromagnetic traps are presented, including the storage time measurement obtained during the 2014 run with antiprotons, the observation of centrifugal separation of a mixed antiproton/electron plasma and positron accumulation and transfer results obtained during 2015..

We describe a system designed to re-bunch positron pulses delivered by an accumulator supplied by a positron source and a Surko-trap. Positron pulses from the accumulator are magnetically guided in a 0.085 T field and are injected into a region free of magnetic fields through a μ -metal field terminator. [...]

Laser excitation of the n=3 level of positronium for antihydrogen production / AEGIS collaboration
We demonstrate the laser excitation of the n=3 state of positronium (Ps) in vacuum. A combination of a specially designed pulsed slow positron beam and a high-efficiency converter target was used to produce Ps. [...]
