Orbit tomography in constants-of-motion phase-space

Nuclear Fusion
Tomographic reconstructions of a 3D fast-ion constants-of-motion phase-space distribution function are computed by inverting synthetic signals based on projected velocities of the fast ions along the diagnostic lines of sight.

2XII Thomson scattering system

, 1973
A Thomson-scattering system using a 6-joule Q-switched ruby laser and an eight-channel polychromator was constructed and employed to measure electron temperatures and densities at the center of the 2XII mirror confinement experiment.

Fast-ion velocity distributions in JET measured by collective Thomson scattering

, 1999
Results on fast ion diagnosis by collective Thomson scattering at JET are presented. 400 kW, 2 mm radiation was scattered in plasmas with energetic proton minority populations heated by 4-8 MW ion cyclotron resonance heating.
