LHCb - Luminosity measurements and PLUME detector at LHCb

Luminosity measurement is a fundamental parameter for all the experiments. The LHCb detector works at a lower luminosity with respect to CMS and ATLAS. It is done by tuning the distance between the two colliding beams according to the measurement of instantaneous luminosity from hardware-based trigg...

description Luminosity measurement is a fundamental parameter for all the experiments. The LHCb detector works at a lower luminosity with respect to CMS and ATLAS. It is done by tuning the distance between the two colliding beams according to the measurement of instantaneous luminosity from hardware-based trigger counters. The upgraded LHCb detector operates at fivefold instantaneous luminosity compared to the previous runs, and it has a fully software-based trigger. Consequently, a new approach to the luminosity measurement is adopted. New counters have been introduced for Run 33. Additionally, in order to verify linearity from calibration to data taking conditions, per-fill emittance scans are performed. For the first time, a new detector capable of measuring the LHC luminosity has been installed at the interaction point of LHCb. It is named Probe for LUminosity MEasurement - PLUME. It enables real time monitoring of beam condition parameters and it provides both online and offline luminosity measurements
