SRGWmb2025 – Storage Rings & Gravitational Waves – mini-brainstorm

10 Feb 2025, 08:30 → 11 Feb 2025, 18:00 Europe/Zurich

6/R-012 - conference room (CERN)

Frank Zimmermann (CERN), Giuliano Franchetti

This 2-day mini workshop on the effect of gravitational waves on the beam in a storage ring is a continuation of larger zoom workshop that was organized during the time of covid,  see https://indico.cern.ch/event/982987/ and https://arxiv.org/abs/2105.00992 .

One goal of the brainstorm is to converge on the relevant equations of motion.
