束流诊断虚拟加速器环境开发（英文）

Development of virtual accelerator environment*for beam diagnostics

为了更好的测试控制方法和开发上层控制软件,本文提出了一种基于ELEGANT和SDDS Toolkit的虚拟加速器环境。在这个虚拟环境下,可以将底层物理模拟软件与上层控制软件通过EPICS控制通道及Matlab脚本进行数据分析及处理。本文描述了在该虚拟加速器环境中束流参数测量和轨道控制等软件的开发和测试,并探讨了该虚拟加速器的设计理念和未来可能的应用。

For the proper operation of Dalian Coherent Light Source （DCLS） linac, measurement and con trol of the electron bunch is essential. In order to test control algorithms and high level physical applications, a virtual accelerator environment is constructed based on ELEGANT code and SDDS Toolkit. The required beam parameter measurement and orbit control tools are tested under this virtual environment and will greatly speed up the development of machine commissioning tools. The design concept and current development status are presented.
