Hefei light source storage ring bunch by bunch 3D position measuring system is introduced and a preliminary study is shown
Ping Lu, Leilei Tang, Baogen Sun +4
The 4 electrode signals of the beam position detector(BPM) of the STORAGE ring of HEFEI Light Source are directly connected to the domestic oscilloscope with 12bit resolution, 10Gs…
Time-delay signature concealed broadband gain-coupled chaotic laser with fiber random grating induced distributed feedback
Yanping Xu, Liang Zhang, Ping Lu +3
A broadband chaotic laser with a flat power spectrum extending up to 8.5GHz is achieved by injecting continuous wave laser light into a chaotic diode laser perturbed by fiber rando…
Time-delay signature suppression in a chaotic semiconductor laser by fiber random grating induced distributed feedback
Yanping Xu, Mingjiang Zhang, Liang Zhang +3
We demonstrate that a semiconductor laser perturbed by the distributed feedback from a fiber random grating can emit light chaotically without the time delay signature. A theoretic…
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…
Transverse beam size measurement system using visible synchrotron radiation at HLS II
Kai Tang, Bao-Gen Sun, Yong-Liang Yang +6
An interferometer system and an imaging system using visible synchrotron radiation (SR) have been installed in HLS II storage ring. Simulations of these two systems are given using…
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 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…
