High Resolution IR Imaging for Alcator C-Mod

We are upgrading the infrared imaging system for divertor heat load studies on Alcator C-Mod by adding a new FLIR SC8303HD camera. The new camera is capable of 1344x784 pixel full frame resolution with 14-bit images at 130 Hz. Faster rates are possible by sub-windowing on the image. The new camera uses full camera link interface over fiber optics from the test cell to the control room, and the resulting data acquisition handles an image stream of 260 Mbytes/second straight to disk. At first we will employ a silicon wafer beam splitter, to enable measurements with both the new and old cameras simultaneously with the existing IR periscope. Initial data from the new camera and the parallel development of real-time imaging software for later use of this hardware on the W7-X stellarator will be discussed.
