Query: A 500 MS/s waveform digitizer for PandaX dark matter experiments   Waveform digitizers are key readout instruments in particle physics
experiments. In this paper, we present a waveform digitizer for the PandaX dark
matter experiments. It supports both external-trigger readout and triggerless
readout, accommodating the needs of low rate full-waveform readout and
channel-independent low threshold acquisition, respectively. This digitizer is
a 8-channel VME board with a sampling rate of 500 MS/s and 14-bit resolution
for each channel. A digitizer system consisting of 72 channels has been tested
in situ of the PandaX-4T experiment. We report the system performance with real
data.
