| 概要 | For the time dependent electron temperature measurement of plasmas, the beam attenuation method using mixed neutral beam of helium and hydrogen is proposed. To optimize the neutral beam source condition for the measurement, ion species ratio of the mixed beam extracted from the bucket type ion source is measured as a function of the helium concentration of the source discharge gas. Taking neutralization efficiency in the beam drift chamber and neutral beam stripping efficiency in the particle detector into account, the helium concentration in the source should be around 0.95. |
