Scientific paper

The public Chandra observations of Cas A reveal spectral variations and knots/features on small scales. Despite its large angular extent, modeling suggests that a grating observation of Cas A may yield high resolution spectral information. N103b in the LMC, is a good candidate for a grating observation in that its overall extent is small, and it shows substructure on the scale of a few arcseconds. Moreover, it is arelatively young SNR, known to have Xray lines at energies well suited to the HETG. Success with a similar observation (E0102 - 72) suggests that this spectrum will yield ejecta velocieties, abundances and plasma conditions.
