/ 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..

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. [...]

Method for measuring positron number in high intensity nanosecond positron bunches based on Poisson statistic
/ Rienäcker, B (CERN) ; Mariazzi, S (Trento U. ; TIFPA-INFN, Trento) ; Povolo, L (Trento U. ; TIFPA-INFN, Trento) ; Guatieri, F (Tech.

Astron.) ; Nebbia, G (INFN, Padua) ; Brusa, R S (Trento U. ; TIFPA-INFN, Trento)
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. [...]
