Smallest vertical beam sizes achieved in high-energy accelerators
arXiv:2506.12361
Abstract
FCC-ee aims at colliding electrons and positrons with vertical rms beam sizes between 30 and 50 nm with beam energies extending from about 40 GeV to 182.5 GeV. In this report, we collect experimental results of different high energy accelerator projects with comparable design vertical beam sizes.
