Abstract

A new high speed IR camera has been successfully implemented and produced reliable heat flux measurements on the lower divertor tiles in NSTX. High spatial and temporal resolutions enable us to investigate detailed structure of heat flux deposition pattern caused by transient events such as ELMs. A comparison with the data with a slow IR camera viewing the same region of interest shows good agreement between the two independent measurements. Data analysis for various plasma conditions is in progress. This work was supported by the U.S. Department of Energy, contract numbers DE-AC05-00OR22725 and DE-AC52-07NA27344.
