Abstract:

During the first quarter of this program several important goals were accomplished. The problem of residual strain in castings of halides KCl and SrCl2 doped KCl and fluorides pure CaFs has been largely overcome by using proper annealing and cooling procedures. Large castings 5 12 in. diameter of CaF2 have been produced with low optical absorption coefficients at 5.25 micrometers. Semi-quantitative analysis of absorption coefficients and scattering centers has been initiated with preliminary results showing a correlation between the two. Reactive atmosphere processing RAC of castings has begun.
