Abstract	The Engineering Validation and Engineering Design Activities for the International Fusion Materials Irradiation Facility (IFMIF/EVEDA) are being pursued under the Broader Approach agreement between EURATOM and the Japanese government. The Linear IFMIF Prototype Accelerator (LIPAc) is under commissioning in Rokkasho, Japan to demonstrate the feasibility of the high duty (CW) and high current (125mA) deuteron beam operation. Currently, the LIPAc beamline is in its final configuration, except for the SRF linac currently replaced by a temporary beam transport line, and is undergoing a high duty cycle RFQ operation up to 5 MeV, which is called Phase B+ and is planned to be completed by the end of June 2024. The major goals of this phase are to validate the RFQ, MEBT and Beam Dump performances at high duty cycle and to characterize the beam properties in preparation to the final configuration with the SRF linac. As of the end of April 2024, a beam current of about 115 mA, a pulse length of up to 3 ms and duty cycle of up to about 4% have been successfully achieved. After the completion of the Phase B+, the SRF will be delivered to the accelerator room and installed in the beamline. This paper will present the results of the Phase B+.
