Application of Libera Photon in Photon Beam Position Measurement System at Hefei Light Source

A new photon beam position processor which named Libera Photon from Instrumentation Technology was introduced at HLS (Hefei Light Source). It had a good resolution better than 0.07 μm, and improved the data efficiency greatly for using embedded EPICS IOC. Matching installations including clock splitter and remote control program were developed. This new photon beam position measurement system was used for the two-wire monitor in the machine diagnostic beam line (MDBL). The photon beam position measured by Libera Photon is similar with beam position measured by BPM at BPM Q8E, which means Libera Photon is suitable to photon beam position measurement.
