The LHC successfully returned to operation in April 2015 after almost 2 years of Long Shutdown 1 (LS1) for various upgrade and consolidation programs. During Run 2 (2015 - 2018) the LHC operated for more than 3600 fills and it has reached a total integrated luminosity of more than 150 fb-1.
This paper summarizes the dynamic vacuum observations in different locations along the LHC during the dedicated fills as well as during the physics runs with different beam parameters. The beam-induced dynamic pressure rise in presence of synchrotron radiation and electron multipacting have been investigated and are presented here. A clear beam conditioning effect has been observed in Run 2.
