Description
AWAKE is the proton-driven plasma-wakefield acceleration experiment at CERN, currently preparing a major upgrade for Run-2c, scheduled to start in 2029. This phase will introduce new beamlines and extended infrastructure, including separate proton bunches-modulation and electron-acceleration stages, achieved in two plasma cells. These planned additions impose complex integration constraints across the facility.
This contribution presents the updated vacuum layout - and its associated remote-control system - and addresses the integration challenges of multiple coexisting systems under vacuum, including the proton and diagnostic beamlines, two electron beamlines with their respective RF e-guns and RF waveguides, IR and UV laser transport lines. Each system features different pressure requirements and dedicated pumping strategies.
Tailored pumping schemes were defined based on expected gas loads, operating scenarios and the limited space available. Analytical conductance and pressure calculations were performed to estimate baseline performance, while Molflow+ simulations were carried out for selected beamlines to characterize pressure profiles and validate the proposed pumping configuration. The contribution summarizes the vacuum-related challenges identified during the design and preparation for Run-2c and provides an overview for the upcoming installation phase.
