LF-MightyPix: A second HV-MAPS prototype for the {LHCb} Mighty-Tracker

Toko Hirono, Sebastian Bachmann, Lucas Dittmann +5

For the future high-luminosity operation of the LHCb experiment, the downstream tracker will be upgraded to the Mighty-Tracker. A key part of this upgrade is the introduction of si…
