First Synchrotron Injection Attempt into The SuperKEKB High Energy Ring
N. Iida, Y. Funakoshi, H. Kaji +17
A synchrotron injection scheme for the SuperKEKB electron high-energy ring (HER) was implemented and experimentally evaluated as the first attempt with a top-up injection during be…
Stable beam operation of approximately 1 mA beam under highly efficient energy recovery conditions at compact energy-recovery linac
Hiroshi Sakai, Dai Arakawa, Takaaki Furuya +37
A compact energy-recovery linac (cERL) has been un-der construction at KEK since 2009 to develop key technologies for the energy-recovery linac. The cERL began operating in 2013 to…
Update of beam coupling impedance evaluation by the stretched-wire method
T. Toyama, A. Kobayashi, T. Nakamura +10
In many cases beam coupling impedances or wake fields are calculated with computer simulator such as CST Studio Suite, GdfidL Electromagnetic Field Simulator and so on. But evaluat…
European Strategy for Particle Physics -- Accelerator R&D Roadmap
C. Adolphsen, D. Angal-Kalinin, T. Arndt +133
The 2020 update of the European Strategy for Particle Physics emphasised the importance of an intensified and well-coordinated programme of accelerator R&D, supporting the design a…
Intra-bunch feedback system developments at DAFNE
Alessandro Drago, INFN-LNF, Frascati +32
This paper presents history and evolution of the intra-bunch feedback system for circular accelerators. This pro-ject has been presented by John D. Fox (SLAC/Stanford Un.) at the I…
The upgrade of J-PARC linac low-level radio frequency system
S. Li, K. Futatsukawa, Y. Fukui +4
The J-PARC linac was consist of 324MHz low-β section and 972MHz high-β section. There is a total of 48 stations. And each station was equipped with an independent LLRF (Low-Level R…
Observation of Vertical Betatron Sideband due to Electron Clouds in the KEKB LER
J. W. Flanagan, K. Ohmi, H. Fukuma +3
The effects of electron clouds on positively-charged beams have been an active area of research in recent years at particle accelerators around the world. Transverse beam-size blow…
Bunch Length Measurements at the ATF Damping Ring in April 2000
K. L. F. Bane, T. Naito, T. Okugi +1
This report presents bunch length and energy spread measurements performed in April 2000 at the ATF Damping Ring, at KEK. Measurements were performed with the beam on and then off…
