  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.
