Abstract : The sixth quarterly technical report for the program to grow large plates of high purity CdTe in a sealed system covers the period April 1 - June 30, 1983. The process to grow 8 inches diameter plates of CdTe high in purity with large grain sizes has been developed. Evaluation results from other workers have conformed the purity and high resistivity of the resultant materials. Attempts to confirm optical homogeneity using an MTF test failed because of our inability to polish the material flat. A method for generating 2 inches diameter disks from the plates was developed. Results from the evaluation of 2 inches disks are presented. The first attempt to produce a 10 inches diameter plate was unsuccessful because of quartz failure. The efforts will be resumed next quarter.
