International Workshop on Higher Order Modes in Superconducting Cavities (HOMSC2025)

6 Oct 2025, 08:00 → 8 Oct 2025, 18:00 Europe/Berlin

DESY, Hamburg

The workshop on Higher Order Modes in Superconducting Cavities will take place on 06 - 08 October 2025 at DESY, Hamburg.

Its objective is to bring together researchers studying higher order mode (HOM) suppression in superconducting RF cavities for applications ranging from energy recovery linacs and light sources to linear colliders. HOMs excited by a beam in superconducting cavities can create excessive heat load on the cryogenic system and dilute beam quality, giving rise to a beam break up instability in the worst case. This workshop will discuss the current status of both experimental and theoretical work in this area. Issues in electron and proton linacs, TESLA style cavities, 3rd harmonic cavities, TEM crabbing and other cavity designs will be considered. Challenges of CW operation as well as uses of HOMs will also be reviewed.
