PandaX-nT升级对电子学系统提出了诸多新的挑战,如更多的通道数、高速高精度的波形数字化、灵活的触发算法和更高的数据带宽要求等。本文介绍一种为未来PandaX-nT暗物质直接探测升级实验预研的读出电子学系统。该电子学系统主要由前置放大电路模块、波形数字化模块(FDM)、数据获取模块(DAQ)和时钟分发模块等组成。FDM集成8路14bit@1GS/s ADC,具有较高集成度,可实现对探测器信号波形数字化,并通过光纤与DAQ通信。DAQ可汇总多块FDM数据,实现全数字化的触发算法,并通过基于TCP协议的千兆以太网与计算机通信,保证了数据传输的可靠与稳定。目前已完成了整个读出电子学系统设计,并对整个电子学系统进行了功能验证,以及与探测器进行了初步的联合测试。整个电子学系统具有较高的可扩展性,并能实现更复杂的触发算法,能满足下一代升级的需求。 |

The upgrade of PandaX-nT brings many new challenges to the electronics system, including more channels,high-speed and high-precision waveform digitization, flexible trigger algorithm and higher data bandwidth requirements.The readout electronics pre-research system was designed for the PandaX-nT dark matter direct detection experiment.The electronics system is mainly composed of pre-amplifier module,frontend digital module (FDM),data acquisition module (DAQ),and clock distribution module.FDM is composed of 8channels 14bit@1GS/s ADC.And it can digitize the detector signal waveform and communicate with DAQ through optical fiber.DAQ is mainly designed for data collection from FDMs and implementation of trigger algorithm. DAQ communicates with the computer through Gigabit Ethernet based on TCP protocol, which guarantees the reliability and stability of data transmission.The electronics has high expansibility and can implement more complex trigger algorithm,which can meet the needs of next generation upgrade.The design and functional verification of the system were completed and the preliminary commissioning tests with the detector were conducted,which indicates the system functions are good. |
