Spectrometry of Captured Highly Charged Ions Produced Following Antiproton Annihilations
F. P. Gustafsson, M. Volponi, J. Zielinski +61
We report a proof-of-principle study demonstrating the first capture and time-of-flight spectrometry of highly charged ions (HCIs) produced following antiproton annihilations in a…
TALOS (Total Automation of LabVIEW Operations for Science): A framework for autonomous control systems for complex experiments
M. Volponi, J. Zieliński, T. Rauschendorfer +52
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…
Real-time antiproton annihilation vertexing with sub-micron resolution
M. Berghold, D. Orsucci, F. Guatieri +63
The primary goal of the AEgIS experiment is to precisely measure the free fall of antihydrogen within Earth's gravitational field. To this end, a cold ~50K antihydrogen beam has to…
