The Electronics and Data Acquisition System for the PandaX-I Dark Matter Experiment

Understand

We describe the electronics and data acquisition system used in the first phase of the PandaX experiment -- a 120 kg dual-phase liquid xenon dark matter direct detection experiment in the China Jin-Ping Underground Laboratory.

• This system utilized 180 channels of commercial flash ADC waveform digitizers.
• This system achieved low trigger threshold ($<$1 keV electron-equivalent energy) and low deadtime data acquistion during the entire experimental run.
