论文摘要
Los Alamos Neu-Tron科学中心（LANSCE）的线性加速器（LINAC）由前束前，主孔，低能束运输（LEBT）组成，四个201.25-MHz Drift Tupl Tube Tube Tube Linacs（DTLS）和405-MHZ COUPLED COUPLED CAVITY CAVITY CAVITY LINACS（CCLS）。作为即将到来的LANSCE现代化项目的一部分，已经数字化了四个201-MHz DTL和26个805-MHz SCLS的低级RF（LLRF）系统。因此，可以对基于网络的腔场和射频连击的控制。每个LLF和高功率RF（HPRF）系统都有许多流程变量（PV）在由可扩展显示管理器（EDM）提供的不同计算机控制屏幕上列出。已经开发了几种MATLAB M-Scripts，以有效地处理必要的PV，同时自动启动，放大器/相校准，对空腔场反馈控制器的增益调整，梁进型控制器的增益和相位调整以及高功率RF RF TRIP恢复，配置和验证过程。本文从RF-Turn-On到Beam FeedForward Control及其相关的EDMS和MATLAB M-Scripts的LANSCE LINAC的RF调试序列。
The linear accelerator (LINAC) at the Los Alamos Neu-tron Science Center (LANSCE) consists of Pre-buncher, Main-Buncher, low-energy beam transport (LEBT), four 201.25-MHz Drift Tube Linacs (DTLs) and forty-four 805-MHz Coupled Cavity Linacs (CCLs). As a part of the upcoming LANSCE Modernization project, low-level RF (LLRF) systems of four 201-MHz DTLs and twenty-six 805-MHz SCLs have been digitized. Hence the net-work-based control of the cavity field and RF commis-sioning are possible. Each LLRF and high-power RF (HPRF) systems have many process variables (PVs) lo-cated on different computer control screens provided by the Extensible Display Manager (EDM). Several MATLAB m-scripts have been developed to efficiently process the necessary PVs while auto-start, ampli-tude/phase calibration, gain tuning of the cavity field feedback controllers, gain and phase tuning of the beam feedforward controllers, and high power RF trip recovery, processes are configured and validated. This paper ad-dresses the sequence of RF commissioning of the LANSCE LINAC from the time of RF-turn-on to beam feedforward control and its relevant EDMs and MATLAB m-scripts.
