Abstract
In the sociology of small- to mid-sized (O(100) collaborators) experiments the issue of data collection and storage is sometimes felt as a residual problem for which well-established solutions are known. Still, the DAQ system can be one of the few forces that drive towards the integration of otherwise loosely coupled detector systems. As such it may be hard to complete with off-the-shelf components only.LabVIEW and ROOT are the (only) two software systems that were assumed to be familiar enough to all collaborators of the AEḡIS (AD6) experiment at CERN: working out of the GXML representation of LabVIEW Data types, a semantically equivalent representation as ROOT TTrees was developed for permanent storage and analysis. All data in the experiment is cast into this common format and can be produced and consumed on both systems and transferred over TCP and/or multicast over UDP for immediate sharing over the experiment LAN. We describe the setup that has been able to cater to all run data logging and long term monitoring needs of the AEḡIS experiment so far.
Highlights
The AEgIS (AD6) experiment is set up at the Antiproton Decelerator (AD) Facility at CERN with the purpose of directly studying the free fall of antimatter in the Earth’s gravitational field [1]

LabVIEW, saving data in local files of disparate formats; collaborators with data analysis experience at CERN tend to be trained in the use of the ROOT [3] analysis framework and the related forms of data object compressed storage; the integrated DAQ and data storage package most commonly used by the antimatter experiment community seems to be MIDAS [4]
