In this presentation we show results of beam profile measurements by a slit-Faraday cup system and a wire scanner. Argon 8+ beams were generated in a new liquid helium-free superconducting electron cyclotron resonance ion source (ECRIS)*, The ECRIS, named SMASHI, was successfully developed at the National Fusion Research Institute in 2014**, and in the future it will be dedicated for highly charged ions matter interaction research facility (HIMIRF). Before designing and constructing HIMIRF terminals after low energy beam transport(LEBT), it is necessary to characterize the beam properties of the source and its LEBT line. The beam profile measurements have been done after an analyzing dipole magnet(DM). The slit-Faraday cup and the wire scanner were installed at 25 cm and 120 cm from the exit flange of AM, respectively. Between the two diagnostics an Einzel lens was positioned to control the focusing of diverged beams. Here, with the measurements we checked the present beam alignments in the LEBT, and studied the dependence of beam profile variation on the operations of beam optics such as steering magnets and Einzel lens..
