An environmental monitoring and control system for the ATLAS ITk Outer Barrel quality control and integration
/ Alvarez, Diego (CERN) ; Joos, Hans L (CERN ; Gottingen U.) ; Kühn, Susanne (CERN) ; Pacifico, Nicola (CERN) ; Pettersen, Jarl N (CERN) ; Pons, Xavier (CERN) ; Vormwald, Benedikt (CERN)
This paper describes the development of a system based on Programmable Logic Controllers (PLC) for safety interlocking and environmental monitoring during ATLAS ITk Outer Barrel (OB) loaded local support quality control (QC) and later integration. The system has been developed at CERN with a focus on scalability, maintainability and reliability, and is expected to be deployed at the different ITk OB loading and integration sites..

The validity of the Weak Equivalence Principle (WEP) as predicted by General Relativity has been tested up to astounding precision using ordinary matter. The lack hitherto of a stable source of a probe being at the same time electrically neutral, cold and stable enough to be measured has prevented highaccuracy testing of the WEP on anti-matter. [...]

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. [...]

Towards the first measurement of matter-antimatter gravitational interaction
/ Evans, C (Milan Polytechnic ; INFN, Milan) ; Aghion, S (Milan Polytechnic ; INFN, Milan) ; Amsler, C (Stefan Meyer Inst. Subatomare Phys.) ; Bonomi, G (U.

The AEgIS (Antimatter Experiment: Gravity, Interferometry, Spectroscopy) is a CERN based experiment with the central aim to measure directly the gravitational acceleration of antihydrogen. Antihydrogen atoms will be produced via charge exchange reactions which will consist of Rydberg-excited positronium atoms sent to cooled antiprotons within an electromagnetic trap. [...]

Compression of a mixed antiproton and electron non-neutral plasma to high densities
/ Aghion, Stefano (Milan Polytechnic ; INFN, Milan) ; Amsler, Claude (Stefan Meyer Inst. 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. [...]
