Design Overview of the Electron Storage Ring Instrumentation System for Hefei Advanced Light Factory | |
|
||
| The Hefei Advanced Light Factory (HALF) is a diffraction-limited storage ring with a beam energy of 2.2 GeV. Based on the beam related technical parameters and requirements provided by the physical design of the HALF storage ring, the storage ring beam instrumentation system mainly includes beam position measurement system, DC current measurement system, bunch-by-bunch beam current measurement system, tune measurement system, beam profile measurement system, bunch length measurement system, bunch-by-bunch feedback system, fast orbit feedback system, BPM displacement measurement system, and beam loss measurement. An overview of the design of the storage ring instrumentation system will be presented. | ||

The Upgrade of the Light Pulse Picking System at HLS-II | |
|
||
|
Funding: National Natural Science Foundation of China under Grant 12075236 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. |
