Description

The ESS linac has been commissioned in two different operation phases operation on the 12 kW commissioning beam dump. In 2025 the linac was operated at full duty cycle in the NCL section (up to 90 MeV) and at reduced duty cycle in the SCL section (up to 870 MeV), due to limitations in the cooling infrastructure and staged implementation of LLRF functionalities. In the present phase the while linac has been operated up to its full duty cycle at 14 Hz and 3.2 ms RF pulses, showing LFD capabilities with long RF pulses in SRF structures.
This contribution summarizes the staged technical commissioning phases, presenting the conditioning experience and the setup for operation at nominal RF performances.
