Effect of the Collision Frequency on the Ion Temperature Determined from Ion Endloss Spectrum

Abstract

We investigate the ion axial confinement time and the ion endloss spectrum in a wide range of collision frequency in a tandem mirror by using Monte-Carlo simulation. It is found that the ion endloss spectrum and the effective temperature determined from the spectrum have a transition depending on the collision frequency. Particularly, in cases where the collision frequency is low, the effective temperature deviate from the field temperature.
