We succeeded in measuring the negative hydrogen ions temperature TH- in the sheet plasma by using an omegatron mass spectrometer. The TH- was determined by measuring the ion current as a function of the ion repeller voltage VG2 using the omegatron mass spectrometer. Calculated using an energy distribution function, TH- was approximately 0.27 eV in the sheet plasma.
