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.

The ESS Target Proton Beam Imaging System has as objective to image the 5 MW ESS proton beam as it enters the spallation target. The Imaging System has to operate in a harsh radiation environment, leading to a number of challenges : development of radiation hard photon sources, long and aperture-restricted optical paths and fast electronics required to provide rapid information in case of beam anomalies. This paper outlines how main challenges of the Imaging System have been addressed, and the status of deployment as ESS gets closer to beam.

The European Spallation Source will be driven by a 5 MW linear accelerator, producing 2.86 ms long proton beam pulses with a peak current of 62.5 mA at 14 Hz. Following the source commissioning in 2018 and 2019, the RFQ was successfully conditioned and subsequently commissioned with beam in 2021. In this paper, we will present results of studies on beam matching to the RFQ, both for low and high current beam modes, and will compare these results to model predictions.

The mechanism of space charge compensation given by the residual gas ionization is a key factor for the emittance containment in the low energy beam transport (LEBT) lines of high intensity hadron injectors. A typical front end including a microwave Ion source, a LEBT and Radio Frequency Quadrupole (RFQ), is equipped with two repellers at each interface to prevent electrons from flowing back, to the source, or forward, to the RFQ. In this paper we will emphasize the importance of the ion Source and LEBT repellers on giving the appropriate boundary conditions for the space-charge compensation building-up mechanism. The theory and simulations are supported by experiments performed in the high intensity facility such as ESS and IFMIF/EVEDA.
