Description
The Advanced Wakefield Experiment (AWAKE) is developing a novel plasma-based accelerator concept in which self-modulated proton bunches generate wakefields capable of accelerating electrons to energies relevant for particle physics. Completed in 2025, the Run 2b experimental phase aimed to demonstrate wakefield-amplitude stabilisation after saturation of the self-modulation process via a plasma density step while establishing the experimental configuration needed for high-quality electron acceleration in Run 2c. In Run 2c, the goal is to demonstrate acceleration up to about 10 GeV while preserving the quality of the accelerated electron beam. To achieve this, a new configuration of the proton transfer line is under investigation to compensate for the bending introduced by the 150 MeV electron line dipole in the interaction region between the two plasma cells. In parallel, the experimental requirements for the 150 MeV electron line have evolved to minimise the physical gap between the two plasma cells, demanding an optimised focusing scheme to deliver a beam with a transverse size of a few microns into the second plasma section. A new design of the 150 MeV electron transfer line is therefore proposed, including detailed error studies to assess its robustness under realistic operational conditions.
