	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.

TUPOJO12	Development of Emittance Meter Instrument for MYRRHA	368

	For the commissioning of the Myrrha proton Linac an Emittance Meter Instrument (EMI) has been foreseen. The EMI will be installed in a dedicated test bench for linac commissioning. The test bench will be initially placed after the RFQ with energies of 1.5 MeV, and in later stages moved to other sections of the Normal Con-ducting Linac for operation at 6 and 17 MeV. The Myrrha EMI will be composed by two slit and grid subsystems for measurement of the phase space in the horizontal and vertical directions. For collimating the beam, graphite slits are used, and the beam aperture is measured in the SEM grids placed downstream. Then, the control system performs signal amplification, data acquisition, and motion control, with the different sys-tems integrated in an EPICs IOC. The system, manufactured by ESS-Bilbao and Proac-tive R&D, has been tested on the ESS-Bilbao 45 keV and soon will be integrated in Myrrha facilities. We present the EMI design, with irradiation analysis and emittance reconstruction, and the integration tests results.

	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.
