Description
As part of the High-Luminosity LHC (HL-LHC) project, the Super Proton Synchrotron (SPS) Low-Level RF (LLRF) system has undergone a major upgrade to meet the performance requirements of the LHC ion program and high-intensity proton beams. A key development in this context is the implementation of a bunch-by-bunch measurement chain, designed to provide high-resolution diagnostics and beam-phase feedback capability.
This tool is particularly valuable for the ion slip-stacking RF manipulations where precise bunch-masking is required. In addition, it serves as a diagnostic tool to investigate beam loading effects by directly comparing the cavity voltage with the phase evolution of individual bunches. The system is implemented on the MicroTCA platform and employs 5-Gsps digitization of the beam signal from a wall current monitor.
This paper presents the operational results and commissioning challenges of the new acquisition and phase loop system.
