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…
A Compact Low-level RF Control System for Advanced Concept Compact Electron Linear Accelerator
C. Liu, L. Ruckman, R. Herbst +11
A compact low-level RF (LLRF) control system based on RF system-on-chip (RFSoC) technology has been designed for the Advanced Concept Compact Electron Linear-accelerator (ACCEL) pr…
High-Power Test of a C-band Linear Accelerating Structure with an RFSoC-based LLRF System
C. Liu, L. Ruckman, R. Herbst +7
Normal conducting linear particle accelerators consist of multiple rf stations with accelerating structure cavities. Low-level rf (LLRF) systems are employed to set the phase and a…
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…
Next Generation LLRF Control Platform for Compact C-band Linear Accelerator
Chao Liu, Ryan Herbst, Larry Ruckman +1
The Low-Level RF (LLRF) control circuits of linear accelerators (LINACs) are conventionally realized with heterodyne based architectures, which have analog RF mixers for up and dow…
