Abstract : This report is concerned with the application of atomic and ionic beams for measurement of electron density and temperature of fusion plasma. The average electron density is determined from the attenuation of an atomic beam. Spectroscopic line ratio measurements along the beam provide information about the electron temperature distribution. Single 'shot' measurements can be made and the data handling automated with an optical Multichannel Analyzer. Atomic cross sections of importance in plasma physics are discussed in two separate sessions.
