Los Alamos has an experimental collaboration with the Alcator C-Mod tokamak at MIT. We have provided a variety of diagnostics, including two fast camera systems, a neutral particle Time of Flight analyzer, and have installed a custom infrared periscope to view the inner armor wall and lower divertor using a digital infrared video camera. In 2004 we are prepared an infrared spectroscopy system, using a 256 element IR detector array and a 0.3 m McPherson 218 spectrometer, to view into the tokamak divertor region, using the existing IR periscope. We tried to observe molecular features in the 0.8-2.5 micron spectral band, but did not have enough throughput with the multi-element periscope (mostly coated for 3-5 micron wavelength). A new 1344x784 FLIR SC8303 IR camera will be installed at Alcator C-Mod, to more than quadruple the spatial resolution of the existing Titanium 550M camera (summer 2012).
A collection of images of the infrared hardware layout, mounted on the top of the Alcator C-Mod concrete igloo, is available as the IR Installation at Alcator C-Mod.
