Description
The Beam Loss Monitors (BLMs) in long straight sections and the dispersion suppressors being covered in the following talk, this presentation focuses on beam losses in the LHC arcs. The main task of the approximately 2200 arc monitors is quench prevention. The arcs are generally very well protected by the collimators. The aim of this talk is to search for possible holes in this protection, and to present the impact of short (single turn to several turn) and/or highly localized losses on the arcs. Among others, leakage from the collimation regions, losses originating from the interaction points and ‘UFO’ type loss have been analyzed.
Possible limits in beam intensity and luminosity will be discussed.
Furthermore, the requirements for BLM system tests following the interventions during the technical stop will be presented.
