论文摘要
Los Alamos中子科学中心（LANSCE）的50年旧级别RF（LLRF）设备的增量升级 - 涉及新的和全部替代机会所没有看到的挑战和问题。截至2022年9月，LANSCE的数字LLF升级已部署了53个所需系统中的30个。本文描述了数字升级，当前状态和未来安装的性能以及技术挑战，包括意外挑战，与与Legacy Alagog设备结合部署新的数字系统有关。此外，本文讨论了使用高能量重新束，梁型特定的设定点和同时在LANSCE的多束操作的同时多能梁操作的操作细节。数字LLRF系统的适应性至关重要，因为该设计能够适应与未来系统相关的新控制和光束参数，而无需进行重大硬件修改，例如预期的LANSCE现代化计划。最近通过模块1、201.25-MHz的高功率RF升级在2021年完成的模块1、201.25-MHz高功率升级。
Incremental upgrades of the legacy low level RF (LLRF) equipment-50 years for the Los Alamos Neutron Science Center (LANSCE)-involves challenges and problems not seen with new and total replacement opportunities. The digital LLRF upgrade at LANSCE has deployed 30 of the 53 required systems as of September 2022. This paper describes the performance of the digital upgrade, current status, and future installations along with the technical challenges, including unexpected challenges, associated with deploying new digital systems in conjunction with legacy analog equipment. In addition, this paper discusses the operational details of simultaneous multi-energy beam operations using high energy re-bunching, beam-type specific set points and simultaneous multi-beam operations at LANSCE. The adaptability of the digital LLRF systems is essential as the design is able to accommodate new control and beam parameters associated with future systems without significant hardware modifications such as the expected LANSCE Modernization Program. This adaptability of the digital LLRF technology was recently demonstrated with the Module 1, 201.25-MHz high-power RF upgrade completed in 2021.
