  Construction and validation of the Linear IFMIF Prototype Accelerator (LIPAc) have been conducted under the framework of the IFMIF/EVEDA project. The LIPAc consists, in its final configuration, of a 100 keV injector and the world longest 5 MeV RFQ accelerator, followed by a MEBT with high space charged and beam loaded re-buncher cavities, an HWR-SRF linac, HEBT with a Diagnostic Plate, ending in a Beam Dump (BD) designed to stop the world highest deuteron current of 125 mA CW at 9 MeV. The beam commissioning at a low duty cycle of ~0.1 % led to a successful RFQ acceleration of 125 mA and 5 MeV beam in 2019. The following beam commissioning phase was initiated in July 2021 with a temporary transport line replacing the SRF linac. The major goals of this phase are to validate the RFQ, MEBT and BD performances up to CW and to characterize the beam properties in preparation to the final configuration with the SRF linac. This paper will present progresses made in this phase so far, such as a low-current and low-duty beam commissioning completed in Dec. 2021, CW operation campaign of the injector towards the nominal beam current, and RF conditioning of the RFQ towards CW.

IFMIF-DONES (International Fusion Materials Irradiation Facility- DEMO-Oriented Neutron Early Source) - a powerful neutron irradiation facility for studies and certification of materials to be used in fusion reactors - is planned as part of the European roadmap to fusion electricity. Its main goal will be to characterize and to qualify materials under irradiation in a neutron field similar to the one faced in a fusion reactor. The intense neutron source is produced by impinging deuterons, from high-power linear deuteron accelerator, on a liquid lithium curtain. The facility has accomplished the preliminary design phase and is currently in its detailed design phase. At the present stage, it is important to have a clear understanding of how the commissioning of the facility will be performed, especially the commissioning of a 5 MW CW deuteron beam, together with the lithium curtain and the beam optimization for the neutron irradiation. In this contribution, the present plans for the hardware and beam commissioning of the accelerator will be given, focusing on the most critical aspects of the tiered approach and on the integration of the procedure with the lithium and tests systems.

  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.
