Abstract
Abstract
A precise characterization of the incoming proton bunch
parameters is required to accurately simulate the self-modulation
process in the Advanced Wakefield Experiment (AWAKE). This paper
presents an analysis of the parameters of the incoming proton
bunches used in the later stages of the AWAKE Run 1 data-taking
period. The transverse structure of the bunch is observed at
multiple positions along the beamline using scintillating or optical
transition radiation screens. The parameters of a model that
describes the bunch transverse dimensions and divergence are fitted
to represent the observed data using Bayesian inference. The
analysis is tested on simulated data and then applied to the
experimental data.
