Development of a setup to measure the timing resolution of the upcoming Mighty Tracker — •Niclas Sommerfeld, Can-Deniz Arslan, Klaas Padeken, Hannah Schmitz, and Sebastian Neubert — Helmholtz-Institut für Strahlen- und Kernphysik Bonn

With the upgrade during LS4, the instantaneous luminosity at the LHCb experiment will increase by almost one order of magnitude to 1.5 × 10³⁴ cm⁻²s⁻¹. With this increased data rate the untriggered readout of the LHCb detector provides changeless for the tracking detectors. The downsteam tracker (Mighty Tracker) will be instrumented with HV-CMOS pixel sensors in the central part. To assign each hit to the correct bunchcrossing, a timing resolution of 3 ns is needed to contain 3 sigma of the hits in a 25 ns window.

To measure the timing resolution of the MightyPix in the lab, a timing setup is required. This ongoing development of a generalized timing layer will be presented within this talk. The setup will consist of fast plastic scintillators with SIPM readouts and configurable, standardized outputs. The modular design allows to use this setup in a variety of applications.
