A Metrology-grade Digitizer for Power Converters in the High Luminosity Large Hadron Collider / Beev, Nikolai (CERN) ; Cerqueira Bastos, Miguel (CERN) ; Martino, Michele (CERN) ; Valuch, Daniel (CERN)
The High Luminosity Large Hadron Collider project at CERN requires performance improvements in the precision powering of magnets, in particular for the new Nb3Sn based Inner Triplet magnets that provide the final focusing of the hadron beams at the interaction points of the ATLAS and CMS detectors. This work presents a new digitizer, the HPM7177, which is part of the signal chain for high precision measurements of magnet current..
