微结构气体探测器因其精度高、面积大等优点,在粒子物理实验中得到了非常广泛的应用。微结构气体探测器的未来应用将面临ASIC种类多、通道数多、数据量大等问题,给读出电子学系统的设计带来了很大的挑战,已成为微结构气体探测器进一步发展应用的瓶颈。FELIX系统具有数据带宽大、通道数多等特点,可很好解决这一问题。基于FELIX的电子学系统由完成探测器信号数字化的前端电子学模块、完成数据汇总的GBT模块、完成数据读出的FELIX系统、完成数据处理的数据处理终端组成,可完成10 240路半数字通道读出或4 096路模拟通道读出。该系统与Micromegas探测器一起实现宇宙线径迹探测,验证了该系统的通用性和兼容性,为微结构气体探测器的应用需求提供了一个通用的解决方案。 |

Micro-pattern gas detectors(MPGDs)have been applied in many fields.With the rapid development of MPGDs,readout electronics system has been a bottleneck to the further application of MPGDs.This paper presents a FELIX-based scalable readout electronics system facing the problem.It consists of pre-amplifier modules,a FELIX which acts as a data router between front-end electronics and DAQ system,2GBT (gigabit transceiver)modules based on FPGA which acts as a bridge between chip carrier and FELIX,and chip carriers whose main function is detector signal conditioning and digitization.The prototype system has 10 240electronic channels applying semi-digital ASIC MICROROC and 4 096electronic channels applying analogue ASIC AGET. Results of joint tests with Micromegas indicate the system works well with different kinds of chip carriers.The design offers a flexible readout solution for different application scenarios of MPGDs. |
