We measured a ground-state vibrational temperature of hydrogen molecule in the high density hydrogen plasma generated on diverter simulator TPD-Sheet IV. The hydrogen plasma generated by gas puffing of hydrogen gases measured electron temperature and density with the langmuir probe. The ground-state vibrational temperature of hydrogen molecules was deduced by applying the corona equilibrium with VUV emission spectroscopy(Lyman Band and Werner Band) in the range from 80 to 140 nm.
