We report on laser cooling of a large fraction of positronium (Ps) in free-flight by strongly saturating the $1^3S$-$2^3P$ transition with a broadband, long-pulsed 243 nm alexandrite laser. The ground state Ps cloud is produced in a magnetic and electric field-free environment. [...]

High-resolution MCP-TimePix3 imaging/timing detector for antimatter physics / Glöggler, L (CERN ; Berlin, Tech. U.) ; Caravita, R (INFN, Trento) ; Auzins, M (Latvia U.) ; Bergmann, B (Prague, Tech. U.) ; Brusa, R S (INFN, Trento ; Trento U.) ; Burian, P (Prague, Tech. U.) ; Camper, A (Oslo U.) ; Castelli, F (Milan U.) ; Cheinet, P (LAC, Orsay) ; Ciuryło, R (Torun, Copernicus Astron. Ctr.) et al.
We present a hybrid imaging/timing detector for force sensitive inertial measurements designed for measurements on positronium, the metastable bound state of an electron and a positron, but also suitable for applications involving other low intensity, low energy beams of neutral (antimatter)-atoms, such as antihydrogen. The performance of the prototype detector was evaluated with a tunable low energy positron beam, resulting in a spatial resolution of 12 mm, a detection efficiency of up to 40% and a time-resolution in the order of tens of ns..

Experiments with mid-heavy antiprotonic atoms in AE$\overline{g}$IS / AEgIS Collaboration
ments which provide the most precise data on the strong interaction between protons and antiprotons and of the neutron skin of many nuclei thanks to the clean annihilation signal. In most of these experiments, the capture process of low energy antiprotons was done in a dense target leading to a significant suppression of specific transitions between deeply bound levels that are of particular interest.

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 a central role in orchestrating the measurement setup: However, its development is often treated as secondary with respect to the hardware, its importance becoming evident only during the operational phase.

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.

High-yield thermalized positronium at room temperature emitted by morphologically tuned nanochanneled silicon targets / AEgIS Collaboration
Nanochanneled silicon targets with high positron/positronium (Ps) conversion rate and efficient Ps cooling were produced. Morphological parameters of the nanochannels, such as their diameter and length, were adjusted to get a large fraction of thermalized Ps at room temperature being emitted into vacuum. [...]

A novel method for the measurement of the number of positrons contained in intense positron bunches is presented. The technique is based on the Poisson distribution of the number of gamma rays emitted by many simultaneous positron–electron annihilations in a small solid angle. [...]

The AEgIS experiment located at the Antiproton Decelerator at CERN aims to measure the gravitational fall of a cold antihydrogen pulsed beam. The precise observation of the antiatoms in the Earth gravitational field requires a controlled production and manipulation of antihydrogen. [...]

Development of a detector for inertial sensing of positronium at AEḡIS (CERN) / AEgIS Collaboration
The primary goal of the AEgIS collaboration at CERN is to measure the gravitational acceleration on neutral antimatter. Positronium (Ps), the bound state of an electron and a positron, is a suitable candidate for a force-sensitive inertial measurement by means of deflectometry/interferometry. [...]
