Multichannel Thomson scattering systems with high spatial resolution (invited)
1986
Thomson scattering systems capable of providing snapshot profiles of electron temperature and density with high spatial resolution (>50 points) have become routine diagnostics on the Princeton large torus (PLT), Princeton divertor experiment (PDX), and tokamak fusion test reactor (TFTR) tokamaks. The design parameters of these systems are compared. Particular attention is given to describing those new components and techniques which have contributed most to improved data quality and reliability in the ten‐year evolution of these systems. Examples of recent TFTR Te(R) and ne(R) profiles are presented.
