LIPAc (linear IFMIF prototype accelerator) beam commissioning & future plans
15
The Linear IFMIF Prototype Accelerator (LIPAc) has been constructed in Rokkasho, Japan to demonstrate the validity of the low energy section of an IFMIF deuteron accelerator up to 9 MeV with a beam current of 125 mA in continuous wave (CW) under the joint collaboration between EU and Japan. The short-pulse 125-mA deuteron beam acceleration to 5 MeV was successfully demonstrated in 2019. Now LIPAc is under commissioning toward the CW beam acceleration. The effort to realize the high-current CW beam, e.g. the commissioning of the ion source at high-current, CW and the conditioning of the RFQ cavity at CW, and the result of the beam commissioning campaign will be presented.

The IFMIF-DONES facility: a fusion-oriented 5 MW superconducting CW linear accelerator
2599
IFMIF-DONES (International Fusion Materials Irradiation Facility, DEMO-Oriented Neutron Early Source) – a powerful neutron irradiation facility for irradiation 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 qualify materials under a neutron field similar to the one faced in a fusion reactor, developing a material database for the future fusion nuclear reactors. The facility is based on an intense neutron source produced by a high current deuteron beam impinging on a liquid lithium curtain, aiming to generate by stripping reactions neutrons with an energy spectrum and flux similar to those expected to be seen by the first wall of a fusion reactor. The IFMIF-DONES facility has accomplished the preliminary design phase and currently in its detailed design phase. The next phase will be the preparation for the construction of the facility. This contribution presents the status of IFMIF-DONES design developed in the framework of the EUROfusion work programme, integrating the lesson learnt from the IFMIF/EVEDA Project (International Fusion Materials Irradiation Facility/ Engineering Validation and Engineering Design Activities - Broader Approach (BA) Agreement signed between EURATOM and Japanese Government), through a common program which includes the different commonalties and interfaces of the two projects. An overview of the present design status of the facility will be provided putting emphasis on the design status of the high current superconducting LINAC, responsible for delivering the 5 MW D+ beam at 40 MeV with very high inherent availability, focusing on the main challenges and the related R&D programme. The prospects for the construction and the commissioning of the facility in Granada (Spain) will be also reviewed.
