Abstract

The layered synthetic microstructure (LSM) technology has made two-dimensional soft x-ray imaging of a tokamak plasma in a single impurity spectral line emission feasible. The curved LSM is used both as an optical filter, with a bandpass in the range of interest on the order of 1.5 Å, and as a focusing optic. A detailed design of a narrow bandpass curved LSM-based pinhole camera, which will image the the region from the scrape-off layer 26 cm into the plasma in the DIII-D tokamak plasma in C vi Lyman α emission at 34 Å, will be presented.
