Description
The AWAKE programme at CERN has evolved from its initial proof-of-principle phase to a comprehensive facility dedicated to advancing proton-driven plasma wakefield acceleration towards first particle-physics applications. In preparation for this next stage, AWAKE will undergo a major upgrade during CERN’s Long Shutdown 3 enabling the demonstration of electron acceleration to 6-10 GeV in a 10 m plasma source with controlled beam quality and validated scalability. Meeting the targets of 5-8% energy spread, 100 pC of accelerated charge and controlled emittance requires strong beam loading. This will be provided by a new RF photo-injector system equipped with two X-band structures and an optimized transfer line, delivering 150 MeV electrons with 5.75 um beam size at injection and 2 mm mrad normalized emittance. In parallel, the 400 GeV SPS proton bunch must reach full self-modulation in the first plasma source (‘self-modulator’) before the electrons are injected into the second plasma source (‘accelerator’). Extensive infrastructure modifications are already in progress, including the dismantling of the CNGS target area in order to create the space required for the upgraded AWAKE facility. We present the consolidated roadmap, the scientific goals, upgrade status and the key challenges associated with both the facility design and the experimental programme starting in 2029.
