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…
Measurement of Sudden Beam Loss Events Using Bunch-by-Bunch BPMs at SuperKEKB
Riku Nomaru, Gaku Mitsuka, Larry Ruckman
At SuperKEKB, sudden beam loss (SBL) events pose a significant challenge to stable accelerator operation. To investigate and better understand SBL, we have developed a new Bunch Os…
Application of RFSoC Technology for Beam Position Monitors at the SuperKEKB Storage Rings Injection Points
B. Urbschat, G. Mitsuka, L. Ruckman
In order to achieve its ambitious luminosity target, the SuperKEKB collider must achieve and sustain high beam currents on the order of Ampere in its storage rings. This requires c…
Implementation and Deployment of an Injection Tuning Tool Using Bayesian Optimization at the SuperKEKB Accelerator
Shinnosuke Kato, Gaku Mitsuka
As of July 2025, the SuperKEKB accelerator, which collides 7 GeV electrons with 4 GeV positrons to abundantly produce particles such as B mesons and tau leptons, holds the world re…
Development of a novel bunch oscillation recorder with RFSoC technology
Riku Nomaru, Gaku Mitsuka, Larry Ruckman +1
The SuperKEKB accelerator is designed to achieve unprecedented luminosity levels, but this goal is currently hindered by Sudden Beam Loss (SBL) events. These events not only obstru…
