Beam Evolution during the 2016 Proton-Lead Run of the LHC — •Marc Jebramcik^1,2, John Jowett¹, Tom Mertens¹, and Michaela Schaumann¹ — ¹CERN, Geneva, Switzerland — ²Goethe University Frankfurt, Frankfurt, Germany

At the end of 2016, the second proton-lead run took place in the LHC. Enabling data taking in no less than 5 experiments resulted in demanding operational conditions due to the different requests of the experiments. These requests included a multiple change of beam directions, switches of the beam energies between 4 Z TeV and 6.5 Z TeV and different demands for luminosity and pile-up. In one month of heavy ion operation, the achieved integrated luminosity came close to the demanded and the measured peak luminosity exceeded several times the unofficial design value.

The different machine settings caused different evolutions of the beam properties, e.g., the beam lifetime and bunch size evolution, which had to be observed cautiously during operation. Simulations as well as first interpretations of the measured data are given.
