Invariant Criterion for the Design of Multiple Beam Profile Emittance and Twiss Parameters Measurement Sections

TL;DR

This paper presents an invariant optimality criterion for designing and comparing multiple beam profile measurement sections, enabling consistent emittance and Twiss parameters assessment regardless of the reconstruction point location.

Contribution

It introduces a novel invariant criterion for designing and evaluating beam measurement sections, independent of the reconstruction point position.

Findings

The criterion allows for optimal design of measurement sections.

It enables comparison of different measurement setups.

The approach is applicable to various beam diagnostics scenarios.

Abstract

We introduce and give examples of applications of an optimality criterion which can be used for the design and comparison of multiple beam profile emittance and Twiss parameters measurement sections and which is independent from the position of the reconstruction point.
