Abstract
The power flow to the DIII‐D divertor targets is routinely measured using infrared (IR) thermography. An IR television camera sensitive to radiation in the 8–12‐μm range views the divertor region using a set of germanium optics. Digital signal processing is used to extract the desired surface temperature profiles from the analog data (≂12 Mbytes) stored on videotape. Inversion of these data using a simple matrix formulation of the inverse heat conduction problem then yields the incident heat flux as a function of space and time. Results from a DIII‐D discharge are included.Keywords
