基于OpenXAL的XiPAF装置虚拟加速器研究

Xi’an 200MeV Proton Application Facility (XiPAF), composed of a 7MeV H- linac injector, a 230MeV synchrotron and two experimental stations, will provide proton beam for the research of single event effect. High-level application plays an important role in construction, commission and operation of XiPAF. Open XAL is a java-based framework used for building high-level accelerator applications. It is an open source version of XAL framework developed by the Spallation Neutron Source (SNS). Open XAL is developed and used by many accelerator laboratory..This project plans to study the construction of XiPAF virtual accelerator based on Open XAL, and develop a set of high-level applications as well as virtual accelerator for XiPAF. Then, we can simulate and study commission process of the machine. Research of the project will not only provide technical support for construction of XiPAF, but also provide methods for design and performance study of similar facilities in the future. An application implementing closed orbit correction with ramping will be developed. Physical models of multipole filed and misalignment errors will also be implemented in virtual accelerator of XiPAF. This work will expand and enrich the existing collaboration of Open XAL with other accelerator laboratories in the world.

西安 200MeV 质子应用装置（XiPAF）由7MeV直线注入器、230MeV同步加速器和两个实验站组成，可提供质子束流用于空间质子单粒子效应研究。加速器高级应用软件研究开发，在西安质子应用装置建造、调束和运行过程中将起重要作用。Open XAL是基于Java语言的高级加速器应用软件构造体系，它是由美国散列中子源SNS发展的XAL高级加速器应用体系的开源版本，由多个加速器实验室开发并使用。项目计划基于Open XAL对XiPAF虚拟加速器的构建开展研究，发展适用于XiPAF的虚拟加速器，在模拟实际机器基础上研究加速器调束和运行过程。项目研究成果不仅可为在建的XiPAF装置提供技术支持，也可为今后类似装置设计和机器性能研究提供重要手段。其中在Open XAL框架下开发升能闭轨矫正程序，在虚拟加速器中建立高阶场和元件准直误差模型等研究尚属首创，这将拓展和充实现有Open XAL国际合作项目。
