Description

The European Spallation Source (ESS) aims to be the world's brightest neutron source, designed to delivering 2 GeV protons at 5 MW to a rotating Tungsten target via a 600 m-long superconducting linear accelerator. At the present installation phase, with 82 of the total 146 cavities available in the superconducting linac, a beam of 800 MeV (2 MW) can be produced. During the first half of 2026, a second commissioning run for the full accelerator had the goal to improve the setup of the machine and to increase the beam power above the levels used during the first run in 2025.
One of the first steps required at the start of each run is to find the amplitudes and phases for each of the cavities for correct acceleration. This paper will give an update on the methods presently used for setup of both the normal conducting and the superconducting part of the machine.
