Description
The Advanced Wakefield Experiment (AWAKE) aims
to accelerate electrons to particle physics relevant energies
using self-modulated proton bunches as drivers in a single
plasma. AWAKE is now in its Run 2b (2023-2024), where
the goal is to stabilise wakefields by using a plasma density step. Experimental demonstrations require probing of the longitudinal wakefields by externally injected electron bunches. To optimise charge capture in the wakefields, the
electron beam density should be maximised at the site of injection ze. This is achieved by setting the beam waist at ze. Since no diagnostics are currently available at these
locations, waist beam sizes are extrapolated from measurements upstream. The qualitative and quantitative agreement obtained between measured and simulated transverse electron beam sizes, at locations where these can be measured,
demonstrates good understanding of the beam line optics and provides confidence in the extrapolated beam sizes at waist locations, where these cannot be measured. This information can then be used in the experiment to maximise the
beam density at the site of injection.
