Compensation of beam-beam and space-charge effects: experience to-date and near-future opportunities

TL;DR

This paper reviews the long-standing challenges of beam-beam and space-charge effects in accelerators, highlighting past solutions and exploring future compensation schemes, especially for electron-ion collider development.

Contribution

It provides a comprehensive overview of past compensation techniques and proposes new schemes for mitigating these effects in future accelerator projects.

Findings

Active compensation has improved beam performance historically.

New schemes are being explored for electron-ion collider applications.

Future opportunities may further mitigate beam-beam and space-charge limitations.

Abstract

Beam-beam interactions and space-charge effects belong to the category of the most long-standing issues in beam physics, and even today, after several decades of very active exploration and development of counter-measures, they still pose the most profound limitations on performance of accelerator facilities. In this brief review we consider past experience in active compensation of these effects and possible new schemes for further exploration in near-future, in particular, within the framework of the electron-ion collider R&D.
