In 2009, the light pulse picking system was built to pick a single synchrotron radiation light pulse from 45 light pulses so that it can be used for researching the longitudinal bunch characteristics at HLS. The optical system was operating well, but the optical pulse picking width was 9.8 ns, which is greater than the bunch interval of 4.9 ns. Therefore, the signal-to-noise ratio of the system is not good enough. The HLS-II light source refers to the machine upgrade project of HLS in 2014. After that, the longitudinal beam characteristics was changed. Therefore, the synchrotron light pulse picking system with better performance has been developed to meet the needs of beam diagnosis and longitudinal beam dynamics research.
