摘　　要：为了测量能量在100 Te V～10 PeV之间宇宙线粒子信息,提出了水契伦科夫探测阵列动态范围扩展系统。设计了水契伦科夫探测阵列动态范围扩展系统读出电路,该电路联合光电倍增管打拿极阳极读出,实现了10 000倍动态范围内高精度的电荷测量,时间测量精度达到20 ns,全量程内分辨率好于10%,线性偏差好于5%。To precisely measure the shower cores of events at the energy range from100 TeV to 10 PeV,we propose the dynamic range extension system of the Large High Altitude Air Shower Observatory-Water Cherenkov Detector Array experiment.The readout electric system for the dynamic range extension system is designed.The circuit combined with the photomultiplier tube is used to achieve a high precision charge measurement within a dynamic range of 10 000 times. The readout electronic system can satisfy the requirement of the extension system,the precision of time measurement reached 20 ns,the resolution of the full range is better than 10%,and the linear deviation is below than 5%.
