Benchmarking of Tomographic Reconstruction Systems for Longitudinal Beam Quality in the Proton Synchrotron

This document investigates and compares the tomographic reconstruction systems for longitudinal beam quality used in CERN’s Proton Synchrotron - the existing Tomoscope application and the newly developed Longitudinal Beam Observation (LBO) system. The presented analysis aims to understand the source of potential differences between the two systems, by investigating discrepancies in each part of the reconstruction pipeline, for different longitudinal beam shapes and energies. This report finds that LBO system is in excellent agreement with the reconstructions from the Tomoscope, with the real discrepancies between the two being minor and likely originating from the acquisition system of the raw data.
