摘要
提出了一种用于热等离子体探测的微通道板信号处理系统的设计方法。可以通过对前置放大器进行阈值控制,从而解决因为微通道板输出电荷积累而造成的增益下降的问题。通过PC端可以实时地观测测量结果。系统中的数据采集处理模块、通信模块、DA控制模块基于FPGA实现,将所有的数字电路环节集成在一个FPGA芯片中,为系统的小型化、稳定性、抗干扰性和在线修改、升级创造了条件,完成了一体化设计。介绍了这种转换的设计思路、硬件框图和软件的实现方法。
A signal processing system to detect the signal from micro-channel plate is presented.With the controlling of pre-amplifier＇s threshold through DA,it can solve the declining of the MCP＇s signal gain.Besides,it provides measurement results form serial debugging assistant.The design of data acquisition and processing module,communication module,DA control module is based on FPGA which Provides solutions for the integrated design.At last,both hardware and the software implement for this design are introduced.
