Development of Measurement and Transverse Feedback System at HLS / Wang, Jun H ; He, Duo-hui ; Li, Wei-min ; Liu, Jian H ; Liu, Zu-ping ; Sun Bao Gen ; Yang Yong Li ; Zheng, Kai ; Zhou, Z R
In order to observe and cure coupled bunch (CB) instabilities caused by the high order modes (HOMs) of the RF cavity and the resistive wall impedance of the Ring vacuum chamber, which were ineluctable during the operation of the accelerator, an observer system characterized by bunch by bunch measurement of transverse ßoscillation and longitudinal synchrotron phase oscillation has been constructed and commissioned at Hefei Light Source (HLS); meanwhile a transverse bunch-by-bunch feedback system is under construction. The design and development of the systems, as well as diagnostics results of machine instabilities will be presented in this paper..

The Measurement of Tune and Phase Space at HLS / Yang Yong Li ; Hong Liu, Jian ; Hua Wang, Jun ; Liu, Zu-ping ; Sun Bao Gen ; Zheng, Kai
Tune and phase space online monitor at the electronic storage ring of Hefei Light Source (HLS) have been realized by using of turn-by-turn beam position data. In this paper, we have compared many methods to compute tune and discussed how to choose the best fitting method for our online tune computing [...]

Bunch Tracing by Bunch by Bunch Measurement System in HLS / Zheng, Kai ; Hong Liu, Jian ; Hua Wang, Jun ; Li, Wei-min ; Liang Yang, Yong ; Liu, Zu-ping ; Sun Bao Gen
In this paper, we introduce a bunch tracing system which is based on a bunch-by-bunch (BxB) measurement system in Hefei Light Source (HLS), and present the analysis of the experiment results. Using an in-phase gate signal and a double balance mixer to control an external trigger of ADC, we test the reliability of the BxB system. [...]

The Commission of Hefei Light Source After Reconstruction / Xu, Hong-liang ; He, Duo-hui ; Li, Wei-min ; Liu, Gongfa ; Liu, Zu-ping ; Shang, Lei ; Sun Bao Gen ; Wang, Lin
After the new four-kicker injection bump system was mounted, it was found that the magnetic field of four-kicker magnet through the same pulse current is different each other, the reason is which the width of pulse magnet fields is not same, so the four-kickers can not form completely local bump, and produce large global orbit distortion,and lead to beam loss. At last we found that the films of ceramic chambers were not plated evenly. [...]
