Design of a CO2-laser Thomson scattering ion-tail diagnostic for Alcator C-Mod

  • 1. Oak Ridge National Laboratory, Oak Ridge, Tennessee 37831 (United States)

Description

A CO2-laser Thomson scattering diagnostic has been designed for the measurement of the ICRH-produced ion tail on Alcator C-Mod. The plasma parameters and port access require that the detection of scattered radiation be made at small angles, typically 1 degree or less. The receiver system consists of five heterodyne detectors and the source laser produces an energy of 10 J per pulse with a 1--5 μs pulse length. The scattering system is currently being installed on the Alcator C-Mod experiment. Details of the diagnostic, calculations of the expected measurements, and application of the diagnostic for ITER are presented
