The bunch current measurement using high-speed photodetector at HLS II
Tian-Yu Zhou, Yong-Liang Yang, Bao-Gen Sun +7
This contribution presents a novel bunch current measurement system based on an ultra-fast photodetector and a high-speed digitizer at Hefei Light Source II (HLS II). In order to a…
Central frequency measurement of the HLS-II storage ring
Jiajun Zheng, Yongliang Yang, Baogen Sun +3
Central frequency is a key parameter of storage rings. This paper presents the measurement of central frequency of the HLS-II storage ring using the sextupole modulation method. Fi…
Beam size and position measurement based on logarithm processing algorithm in HLS II
Chaocai Cheng, Baogen Sun, Yongliang Yang +9
A logarithm processing algorithm to measure beam transverse size and position is proposed and preliminary experimental results in Hefei Light Source II (HLS II) are given. The algo…
A new measurement method of electrode gains for orthogonal symmetric type beam position monitor
J. Y. Zou, F. F Wu, Y. L. Yang +5
The new beam position monitor (BPM) system of the injector at the upgrade project of Hefei Light Source (HLS II) has 19 stripline beam position monitors. Most consist of four ortho…
A waveguide overloaded cavity kicker for the HLS II longitudinal feedback system
Wubin Li, Zeran Zhou, Baogen Sun +4
In the upgrade project of Hefei Light Source (HLS II), a new digital longitudinal bunch-by-bunch feedback system will be developed to suppress the coupled bunch instabilities in th…
