The 2017 Xe run at CERN Linac3: Measurements and beam dynamics simulations

At CERN, large hadron collider heavy ion and super proton synchrotron fixed target experiments are performed thanks to the Heavy-ion Facility, composed of different accelerators. The starting point is Linac3, which delivers 4.2 MeV/u ion beams to the low energy ion ring. In 2017, Linac3 accelerated Xe instead of the most usual Pb. This article summarizes the measurements performed during the machine development time allocated to characterize the line from the source to the filtering section. A parallel effort was devoted to matching those measurements to the beam dynamics simulations, and the second part of the article highlights the results achieved in this regard. Thanks to the improved understanding of the machine critical areas, a list of possible improvements is proposed at the end.
