NSTXNSTX NSTX Monday Physics Meeting – First results of fast IR camera (Ahn) 2June 22, 2009

Summary

• The new fast IR camera is working reliably to measure divertor heat flux with temporal resolution of 1.6 - 6.3kHz and spatial resolution of 6.4mm

• Temporal resolution is fast enough to resolve transient

events

• Time averaged temperature and heat flux profiles agree well with slow IR data

• Data analysis for various plasma conditions in progress
