CERN technologies: from fundamental research to our everyday lives. Since 1954, the world-class research performed at CERN helps uncover what the universe is made of and how it works: here, scientists from all over the world study elementary particles – invisible to the eye – through complex and often gigantic instruments.

LHCb - The LHCb Scintillating Fibre Tracker
Reference: Poster-2023-1129
Note: dimitrios.kaminaris@cern.ch; lukas.witola@cern.ch
Created: 2023. -1 p
The LHCb detector underwent a major upgrade in the past years. The modifications enable the detector to operate at an increased instantaneous luminosity and to read out data at the LHC bunch crossing rate of 40MHz. The new operating conditions required the replacement of the complete tracking system. The main tracking stations are replaced by the SciFi Tracker, a large high granularity scintillating fibre tracker read out by arrays of silicon photomultipliers (SiPMs). A custom ASIC is used to digitise the SiPM signals at 40MHz using three comparators per channel. Further digital electronics perform clustering and data-compression before the data is sent via optical links to the DAQ system. The comparator thresholds are calibrated using a dedicated light injection system. The commissioning of this system, calibration results, and latest performance measurements are presented in this poster. The SciFi Tracker has three stations with four detection layers each and uses the BCAM system for real-time 3D monitoring. Originally developed for the ATLAS experiment, BCAM uses opto-electronic sensors to monitor the detector geometry detecting shifts or deformations caused by factors like LHCb magnet powering cycles, SciFi detector powering, or environmental variations. Preliminary results highlight BCAM's micron-level sensitivity (10-20 microns) and its effectiveness in monitoring the impact of magnetic fields and operational conditions on the detector alignment.
