摘　　要：在LECR3离子源低能束流传输线(LEBT)束流调试过程中,需要将荧光靶采集到的束流信息通过数值计算、传输和图形显示等处理,实现束流品质参数的可视化功能,以方便束流诊断和调试。为此,研制了基于EPICS(Experimental Physics and Industrial Control System)的荧光靶剖面参数测量及分析的在线可视化系统SOMS(Scintillator Online Measurement System),其中IOC(Input Output Controller)层是通过Python数据处理程序编程,实现了荧光靶图像获取、标定、处理,及剖面参数计算、参数PV(Process Variable)发布的软件功能模块,并在CSS(Control System Studio)客户端实现了荧光靶图像剖面参数可视化功能。整套系统通过载束运行测试,结果显示,系统运行稳定、可靠,束流剖面参数计算准确、快捷,用户界面友好,提高了离子源前端束流调试效率。During the beam commissioning of the Low Energy Beam Transport(LEBT)line of the LECR3 ion source,it is necessary to process the beam transverse profile collected by the fluorescent target through numerical calculations,transmission,and graphical display,to achieve the visualization of beam quality parameters,facilitating beam diagnostics and tuning.To achieve this,an online visualization system for measuring and analyzing fluorescent target profile parameters,known as the Scintillator Online Measurement System(SOMS),has been developed based on the Experimental Physics and Industrial Control System(EPICS).Within this system,the Input Output Controller(IOC)layer is implemented using Python data processing scripts,which facilitate software modules for image acquisition,calibration,processing,calculation of profile parameters,and publication of parameters as Process Variables(PV).Moreover,the visualization of fluorescent target image profile parameters is integrated into the Control System Studio(CSS)client.The entire system has undergone beam operation testing,demonstrating stable and reliable performance,with accurate and efficient calculations of beam profile parameters.The user interface is designed to be intuitive,significantly enhancing the efficiency of beam commissioning at the front end of the ion source.
