Tomographic analysis of the evolution of plasma cross-sections

Creators

Description

A diagnostic has been developed for measurements of the evolution of plasma density distributions in 2D using the principles of computed emission tomography. The system measures the near infrared emission along several chords through the plasma cross-section and the emission profile is then reconstructed using a maximum entropy based algorithm. This paper will present details of the reconstruction algorithm; the data collection system; the verification of the diagnostic using both physical and numerical phantom sources; evidence for the correlation between n2 and the infrared emission intensity; initial measurements on a tokamak plasma
