Description

At the China Jinping Underground Laboratory, the PandaX-4ton ( Particle AND Astrophysical Xenon phase IV) in planning is a dark matter direct detection experiment with dual-phase Xenon. PandaX-4ton, compared to PandaX-II, has more readout channels and higher time precision requirements. Once incoming WIMPs (Weakly Interacting Massive Particles) collide with Xenon atom, prompt scintillation photons (S1) and delayed electroluminescence photons (S2) are collected by the PMTs, and then fed into front-end electronics which are introduced in this paper. In order to precisely obtain the wave and time information carried by the PMT signals, and to maximally cover the signal dynamic range, a high-gain preamplifier and an eight-channel digitizer with 14-bit resolution and 1 GSps sampling rate have been designed. Besides, the clock synchronization circuit within the digitizer is well-designed to align all the PMT channels. The digitizer also contains gigabit fiber to exchange data with trigger and data acquisition system. The performance of the front-end electronics can meet the requirements for the PandaX-4ton.
