Speckle interferometry diagnostic for erosion/redeposition measurement in tokamaks

Funded under: FP7-EURATOM

Abstract

For erosion/redeposition measurement in tokamaks, an optical method based on temporal phase shifting speckle interferometry is in development at CEA Cadarache. Measurement performed on carbon material allowed us to develop a procedure for erosion/redeposition measurement during a plasma discharge. In order to measure reliable amount of eroded and redeposited material in tokamaks during a plasma discharge, the optical method has been adapted to tokamaks environment. Such improvements allowed to perform shape measurements on ITER divertor mock-up and erosion measurement on the Toroidal Pumped Limiter in realistic tokamak conditions.
