Research Abstract	We have developed a residual gas ionization beam current monitor (RGICM), which can monitor intense semi-DC proton beams at J-PARC Hadron Experimental Facility with non-destructive feature and less than 10 % accuracy. A prototype RGICM has been tested with 50 MeV proton beam at Research Center for Nuclear Physics, Osaka University, and showed good linearity of less than 7%. The prototype monitor has been installed in the proton beam line at J-PARC Hadron Experimental Facility, and tested with 30 GeV proton beams. The relative stability of the monitor with 30 GeV proton beams was less than 10%. The results indicate that the residual gas ionization profile monitor is useful for semi-DC proton beams at J-PARC.
