Impact of Field Errors of Quadrupole Units on Beam Losses at SIS100 Injection

TL;DR

This paper investigates how field errors in quadrupole units affect beam losses in SIS100 during injection, using recent cold measurements and comparisons with a standard quadrupole unit.

Contribution

It provides new insights into the impact of field imperfections on beam losses by analyzing recent measurements of quadrupole units in SIS100.

Findings

Field errors contribute significantly to beam losses.

Cold measurements reveal differences between series and first-of-series units.

Understanding these errors can improve beam stability and machine performance.

Abstract

This report discusses heavy-ion beam losses due to the nominal transverse space charge and the field imperfections in SIS100 during accumulation based on recent cold measurements of the first 10 series quadrupole units. They are compared to the (stamped) First-of-Series quadrupole unit #2.
