| Abstract | In 2023, about 2 months of LHC operation were devoted to Heavy Ion physics. In this paper, results of the 2023 ion optics commissioning are reported. Local corrections in Interaction Points (IP) 1 and 5 were reused from the earlier proton commissioning. The optics measurements, however, revealed an energy offset at the level of 10−4 for both beams, correction of which helped reduce the residual optics errors in IP1 and IP5. Optics measurements also showed the need for new local corrections in IP2. This, together with global corrections at top energy, allowed a 𝛽-beating of about 5% to be reached for the collision optics. Dedicated measurements during the energy ramp also later revealed a large 𝛽-beating, consistent with an energy mismatch. |
