Speaker
Description
The European Spallation Source (ESS) has recently completed beam commissioning up to the tuning beam dump, reaching a proton energy of 800 MeV. This talk will focus on the technical commissioning of the linear accelerator, covering both the normal-conducting and superconducting sections, as well as the testing and integration of superconducting cryomodules. We will describe the phased commissioning process, including high-power RF conditioning of the normal-conducting cavities, superconducting RF (SRF) cavities, and power couplers. Highlights from cryomodule installation, cooldown, and performance testing will be presented. The talk will also discuss integration challenges, cross-functional coordination, and key lessons learned during this phase. Selected results will demonstrate the system’s readiness for high-power beam operation and outline the next steps in ESS commissioning.
