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
The goal of the AEgIS experiment is to measure the gravitational acceleration of antihydrogen – the simplest atom consisting entirely of antimatter – with the ultimate precision of 1%. We plan to verify the Weak Equivalence Principle (WEP), one of the fundamental laws of nature, with an antimatter beam. [...]

AEgIS Experiment: Status & Outlook
/ Lansonneur, P (Lyon, IPN) ; Aghion, S (Milan, Polytech. ; INFN, Milan) ; Amsler, C (Stefan Meyer Inst. Subatomare Phys.) ; Bonomi, G (U. Brescia ; INFN, Pavia) ; Brusa, R S (Trento U. ; TIFPA-INFN, Trento) ; Caccia, M (INFN, Milan ; Insubria U., Como) ; Caravita, R (Genoa U. ; INFN, Genoa) ; Castelli, F (INFN, Milan ; Milan U.) ; Cerchiari, G (Heidelberg, Max Planck Inst.) ; Comparat, D (LAC, Orsay) et al.
The AEGIS experiment 1 (Antimatter Experiment: Gravity, Interferometry, Spectroscopy) is planned to perform the first measurement of the gravitational acceleration on antimatter by observing the free fall of antihydrogen atoms. By combining techniques based on recent developments in the production of positronium and its laser excitation to Rydberg states, such a study seems indeed to be feasible for neutral antimatter.

The AEgIS experiment carried out at CERN aims to form a cold antihydrogen beam to perform precision studies on gravity. A key ingredient is the creation of antihydrogen via a charge-exchange process between trapped antiprotons and Rydberg excited positronium atoms (Ps). [...]

The AEgIS experiment at CERN aims to perform the first direct measurement of gravitational interaction between matter and antimatter by measuring the deviation of a cold antihydrogen beam in the Earth gravitational field. The design of the experiment has been recently updated to include emulsion films as position sensitive detector. [...]
