The LIPAc consists of an injector, an RFQ, MEBT, a diagnostic plate, HEBT, and a beam dump. Each component was aligned within an accuracy of +/-0.2 mm in the beamline, however, a misalignment of about 0.5 mm in the horizontal direction between the RFQ and the 1^st quadruple magnet of MEBT was recently measured by the alignment survey with a laser tracker. We carried out the beam-based alignment for MEBT components and evaluated misalignments for each component. In this meeting, the results of comparisons between laser-based alignment and beam-based alignment will be reported.
