Testing of Cold Electronics for ProtoDUNE-SP TPCs

The ProtoDUNE single-phase and dual-phase detectors in the neutrino platform at CERN serve as prototypes for the horizontal drift and vertical drift modules respectively of the future DUNE experiment. Each detector has dedicated beamlines through which they receive a variety of 0.3-0.7 GeV secondary particles originating from the CERN Super Proton Synchrotron. Following a successful first run in 2018, the DUNE collaboration is currently preparing for a second run with increased beam statistics and improvements to all detector elements. An overview of the cold readout electronics for the DUNE and ProtoDUNE time projection chambers will be presented followed by a description of the procedure for QC testing of the custom waveform digitizer that was designed for DUNE and the results of tests done in preparation for the upcoming ProtoDUNE running.
