Characterization of Losses in LHCb — Johannes Albrecht¹, Federico Alessio², Elena Dall'Occo², and •David Rolf¹ — ¹TU Dortmund University, Dortmund, Germany — ²CERN, Geneva, Switzerland

The LHCb experiment is one of the four large particle detectors at the LHC. One important aspect of the experiment is to perform very precise measurements of rare b and c quark decays.

A very clean signal is required during nominal collisions. Operating the LHC comes with different sources of background particles induced from machine operation (MIB). These particles can collide with the collimators shielding the experiment causing secondary showers onto the detector.

In this talk the sources of such losses are explained. The losses are characterized by performing dedicated loss runs. The potential effect on the detector and the physics impact is studied.
