Abstract
Crystal collimation was investigated for possible deployment in the Large Hadron Collider (LHC). A prototype layout, integrated in the betatron collimation insertion (IR7), is used to assess the performance and compare it to the standard system. This was tested in different conditions with proton and lead ion beams. A special run with fully-stripped xenon ion beams at 6.5Z TeV was carried out in 2017 and provided a unique opportunity to test the crystal collimation system with a new ion species. In this paper the results recorded with Xenon beams, which show promising collimation cleaning results, are presented.
