	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 first tank of Drift Tube Linac (DTL) for the European Spallation Source ERIC (ESS), delivered by INFN, has been installed in the ESS tunnel in Summer 2021. The DTL-1 is designed to accelerate a 62.5 mA proton beam from 3.62 MeV up to 21 MeV. It consists of 61 accelerating gaps, alternate with 60 drift tubes equipped with Permanent Magnet Quadrupole (PMQ) in a FODO lattice. The remaining drift tubes are equipped with dipole correctors (steerers), beam position monitors (BPMs) or empty. The total length of the cavity is 7.6 m and it is stabilized by post couplers. Two waveguide couplers feed the DTL with the 2.2 MW of RF power required for beam operation, equally divided by RF power losses and beam power. This paper first presents the main systems required for the DTL conditioning. Then it summarizes the main steps and results of this high power RF conditioning done at ESS to prepare the DTL for the consequent beam commissioning.

	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.

	RFQ at ESS has been successfully gone through RF conditioning, RF re-conditioning and low duty cycle beam commissioning. RFQ fulfills required functions and overall performance is satisfactory. RF conditioning, three RF re-conditionings after LEBT intervention and beam commissioning will be reported and RFQ performance during these periods will be described. RFQ performance in a large extent is reflected by dynamics and interactions between RF, cavity and beam. Thanks to advanced hardware capabilities and intelligent software intelligence, observation of those dynamics and interactions are done in detailed level. Analysis of those dynamics and interaction will be introduced. Some techniques to deal with challenges resulted from those dynamics and interactions will also be discussed.
