Two parallel tune measurement systems are installed at GSI SIS-18 based on different
principles. The first is called the Tune, Orbit and POSition measurement system TOPOS. Its …

A signal generator for transverse excitation of stored particle beams is developed and
commissioned at GSI SIS18. Thereby a novel approach using a software-defined radio …

Abstract Direct Diode Detection (3D) is a technique developed at CERN initially for the LHC
tune measurement system, to reach a sensitivity allowing observation of beam betatron …

In order to further probe our understanding of the structure of matter and the universe,
physicists constantly strive to create particle colliders that reach higher energies and …

Beam diagnostics and instrumentation are an essential part of any accelerator. There is a
large variety of parameters to be measured for observation of particle beams with the …

It is well known that in a superconducting accelerator a significant chromaticity drift can be
induced by the decay of the sextupolar component of the main dipoles. In this paper we give …

Abstract Machine learning (ML) has become a valuable tool in particle accelerator control,
with growing potential for beam parameter correction. In this study, we present preliminary …
