Description
As the LHCb experiment transitions to the conditions imposed by the High-Luminosity LHC, the performance requirements for it's detectors will increase significantly. To meet these demands, all detectors in LHCb will undergo an upgrade during long shutdown 4 in 2035, collectively called Upgrade II. One of the most significant design changes will be applied to the SciFi tracking detector which will be upgraded to the Mighty Tracker, consisting of an outer region instrumented with the existing SciFi scintillating fibres, and an inner region instrumented with pixelated silicon tracking detectors. This contribution will present the lab characterisation of the LF-MightyPix, a prototype MightyPix High-Voltage CMOS (HV-CMOS) silicon pixel sensor. The final MightyPix design is a candidate for installation in MightyTracker. Also presented are results from a HV-CMOS serial powering prototype, developing a feature vital for the final detector.
