摘要
描述了二期工程中NSRL电子储存环束流位置监测系统的升级及其数据获取 .介绍了BergozBPM电子学信号处理模块和基于VXI的数据获取模块以及网络互连技术在闭轨测量系统中的应用 .LabVIEW软件开发环境则提供了好的硬件控制 ,提高了开发效率 .升级后的束流位置测量系统在线监测误差 ,即它的长期可重复性≤ 1 0 μm ,处理电子学分辨率可达 1 μm .
In this paper, the upgraded BPM system including the data acquisition instrumentation of HLS in NSRL phase II project are described in details. In the upgraded BPM system, we wash out the multiplexer relay switch system for signal transmit formerly and adopt paratactic signal processing. Bergoz's analog BPM modules and modular VXI instruments are adopted for BPM signal processing and data acquisition in order to provide stable and credible performance. The Lab VIEW developement environment not only provides good hardware controls but also promotes the development efficiency. After upgrade the new COD system with repetition error≤10μm and resolution 1μm is achieved in routine operation. Lately using the upgrade COD system we have completed the measurement of dispersion and one of magnetic field center for quadrupole magnet in beam based alignment(BBA) with local bump orbit, and have processed the experiment of global close orbit correction for HLS storage ring.
