Abstract

The operation of the updated BPM system of HLS and the VXI-based application of LabVIEW as well as Network technic in the NSRL phase II project, are introduced here. The Bergoz BPM modules and the modular VXI measurement instruments are adopted for data measurement and acquirement, in order to provide stable and credible performance. The LabVIEW development environment of VXI-based, which is adopted in our project, not only provides good hardware controls, but also promotes the development efficiency. The measured data is fed back to correct closed orbit of the storage ring in constant time interval. At the same time, another copy of the measured data is sent to an independent data-server to be recorded. The BPM system now works with a precision not greater than 10 μm, and a resolution about 1 μm
