  The European Spallation Source, currently under construction in Lund Sweden, will be a spallation neutron source driven by a superconducting proton linac with a design power of 5 MW. The linac features a high peak current of 62.5 mA and long pulse length of 2.86 ms with a repetition rate of 14 Hz. The normal conducting part of the linac has been undergoing beam commissioning in multiple steps, and the main focus of the beam commissioning has been on bringing systems into operation, including auxiliary ones. In 2022, beam was transported to the end of the first tank of the five-tank drift tube linac. This paper provides a summary of the beam commissioning activities at ESS and the current status of the linac.

  The European Spallation Source (ESS) aims to build and commission a 2 MW proton linac ready for neutron production in 2025. The normal conducting section of the ESS linac is designed to accelerate a 62.5 mA proton beam to 90 MeV at 14 Hz. The section consists of a microwave ion source, Radio Frequency Quadrupole (RFQ) and 5-tank Drift Tube Linac (DTL). All sections are provided to ESS by in-kind partners across Europe. This paper reports the recent progress on the assembly, installation, testing and commissioning of the ESS normal conducting linac.

  The latest beam commissioning phase of the Normal Conducting Linac at ESS delivered a proton beam through the Medium Energy Beam Transport (MEBT) into the first Drift Tube Linac (DTL) tank. The probe beam in MEBT consisted of 3.6 MeV protons of <6 mA, <5 microseconds pulse length and 1 Hz repetition rate. Following the delivery of the components at ESS in Lund in June 2019, the commissioning phase with the MEBT was completed in July 2022. In March 2022, the maximum beam current of 62.5 mA was transported up to the MEBT Faraday cup. This proceeding focuses on the status of MEBT including magnets, buncher cavities, scrapers and beam diagnostics designed and tested in collaboration with ESS Bilbao.

  Within the framework of the plans for study of a light-ion linear accelerator, ESS Bilbao is manufacturing a radio frequency quadrupole (RFQ) aimed at accelerating up to 3 MeV the protons generated in the ion source. The progress made and the difficulties encountered with the RFQ are discussed in this paper. A power coupler proto-type for the RFQ has been developed while several me-chanical constraints were also studied in the final cou-pler. This prototype operates at a lower power, then it can work using PEEK window for the vacuum interface and it does not require neither brazing nor cooling system. Also, a complete RF test stand is being implemented to perform the high-power conditioning in traveling and standing wave mode, to verify the power handling capa-bility of the coupler and its thermal behaviour. The RF test stand, based on EPICS environment, can provide up to 2 MW peak power at 352.2 MHz in a pulse operation of 14 Hz and a duty cycle of 4.9%.
