An important cryogenic equipment of the Large Hadron Collider (LHC) consists in the electrical distribution feedboxes (DFBs) which are used to power the superconducting magnets of the accelerator. These feedboxes contain the current leads achieving t

Since 2012, the e-clouds produced by LHC beams are inducing significant dynamic heat loads on the LHC cryogenic system. These additional heat loads are deposited on beam screens where they must be properly extracted by the cryogenic system between 4.

A consequence of the formation of electron cloud in beam chambers is the deposition of energy on their walls due to electron impacts. In cryogenic devices this can cause a significant heat load for the cryogenics system, posing constraints on machine

The first part of the presentation will summarize the overall cryogenic performance and availability for 2017 and the expected performance for 2018 taking into account the beam induced heat loads in the inner triplets magnets and the beam screen circ

The first part of the presentation will summarize the overall cryogenic performance and availability for Run 2. Main evolutions and effects on the cryogenic system during Run 2 will be presented. The second part will focus on the LS2, in particular t

During Run 2, the 25 ns bunch spacing was routinely used for proton physics operation at the LHC. With this bunch spacing, electron cloud effects are significantly more severe than with the 50 ns spacing, which had been used for luminosity production
