Description
The LCLS-II-HE project is a high-energy upgrade to the existing LCLS-II superconducting linac at SLAC, designed to increase the beam energy from 4 GeV to 8 GeV. This upgrade includes the addition of 184 high-energy (HE) SRF cavities operating at an average gradient of 22 MV/m, supplementing the 280 existing LCLS-II SRF cavities. To support these new cavities, the HE LLRF project will deploy 46 LLRF rack systems to provide precise RF field regulation—meeting amplitude and phase stability requirements of 0.01% and 0.01° RMS, and resonance control to maintain average cavity detuning below 1 Hz. This paper presents an overview of the HE LLRF project status, reviews system updates, and discusses readiness for the upcoming LLRF installation and checkout, along with key lessons learned throughout the project lifecycle.
