VELO Upgrade Module Characterization

During Run I and II, the Large Hadron Collider Beauty (LHCb) Experiment acquired proton-proton collisions data with an instantaneous luminosity of $\mathrm{4 \times 10^{32}}$ $\mathrm{cm^{-2}}$ $\mathrm{s^{-1}}$. Through the long-shutdown two (LS2), most of the LHCb sub-detectors are being upgraded due to the new data-taking conditions which include an increase of factor 5 on the instantaneous luminosity. VErtex LOcator (VELO) is a detector designed surrounding to the interaction point. Its main purpose is the reconstruction of tracks of p-p collisions and decay vertices. The new hybrid pixel vertex detector will feature modules based on microchannel cooling substrates and $\mathrm{55 \times 55}$ $\mathrm{ \mu m^2}$ pitch pixel detectors bump bonded to ultra high speed ASICs which operates at 40 MHz called the Velopix. CERN VELO Lab has the important role of testing and debugging VELO module prototypes. My contribution related to the operation of a setup for testing these modules during the Summer Program is reported
