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. [...]

CIRCUS: an autonomous control system for antimatter, atomic and quantum physics experiments
/ AEgIS Collaboration
A powerful and robust control system is a crucial, often neglected, pillar of any modern, complex physics experiment that requires the management of a multitude of different devices and their precise time synchronisation. The AEgIS collaboration presents CIRCUS, a novel, autonomous control system optimised for time-critical experiments such as those at CERN's Antiproton Decelerator and, more broadly, in atomic and quantum physics research. [...]

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.

Gravity and antimatter: the AEgIS experiment at CERN
/ Pagano, D (INFM, Brescia ; INFN, Pavia) ; Aghion, S (Bergen U. ; INFN, Milan) ; Amsler, C (Stefan Meyer Inst. Subatomare Phys.) ; Bonomi, G (INFM, Brescia ; INFN, Pavia) ; Brusa, R S (Trento U. ; TIFPA-INFN, Trento) ; Caccia, M (INFN, Milan ; Insubria U., Como) ; Caravita, R (CERN) ; Castelli, F (INFN, Milan ; Milan U.) ; Cerchiari, G (Heidelberg, Max Planck Inst.) ; Comparat, D (LAC, Orsay) et al.
From the experimental point of view, very little is known about the gravitational interaction between matter and antimatter. In particular, the Weak Equivalence Principle, which is of paramount importance for the General Relativity, has not yet been directly probed with antimatter. [...]

Protocol for pulsed antihydrogen production in the AE$\overline{g}$IS apparatus
/ Tietje, I C (CERN ; Berlin, Tech. U.) ; Amsler, C (Stefan Meyer Inst. Subatomare Phys.) ; Antonello, M (Insubria U., Como ; INFN, Milan) ; Belov, A (Moscow, INR) ; Bonomi, G (INFM, Brescia ; INFN, Pavia) ; Brusa, R S (Trento U. ; TIFPA-INFN, Trento) ; Caccia, M (Insubria U., Como ; INFN, Milan) ; Camper, A (CERN) ; Caravita, R (TIFPA-INFN, Trento) ; Castelli, F (INFN, Milan ; Milan U.) et al.
The AEḡIS collaboration’s main goal is to measure the acceleration of antihydrogen it ($\textit{H}$) due to gravity. The experimental scheme is to form a pulsed beam whose vertical deflection is then measured by means of a moiré deflectometer [1]. [...]

A ∼100 μm-resolution position-sensitive detector for slow positronium

In this work we describe a high-resolution position-sensitive detector for positronium. The detection scheme is based on the photoionization of positronium in a magnetic field and the imaging of the freed positrons with a Microchannel Plate assembly. [...]

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. [...]
