The microwave-induced helium plasma generated at atmospheric pressure in the TM010 resonant cavity is attractive as an excitation source for emission spectrometry. The efficiency of the cavity produces an extremely high energy-density plasma and its short longitudinal dimension permits close spatial and photometric monitoring system proximity between the plasma and different types of sampling devices. Examination of the electron density, excitation temperature and rotational temperature in this microwave plasma reveals its unusual character and suggests certain mechanisms of operation. Author
