Abstract : The document reports progress toward improving the ruby growth process for the manufacture of Rangefinder laser rods. The work of the first quarter involved procurement of equipment, preliminary growth of crystals, improvement of growth apparatus, and initial runs investigating individual variables of the Verneuil growth process. Preliminary growth was performed: viz., shakedown for the two stations assigned to the project, and determination of the present status of crystal growth performed on two additional stations on temporary loan. The crystals produced in the latter investigation await evaluation. A means for accurately controlling the distance between the boule cap and the burner head was devised and installed and is now operating satisfactorily. A means for obtaining a continuous flow of powder was devised. This apparatus will be installed and tested on a growth station during the next quarter. Investigations of the effect of varying the diameter of the boule and the distance between the boule cap and the burner are well under way. Crystals produced in these investigations now await evaluation. All items on the critical path of the PERT diagram are on or ahead of schedule. Fabrication and active evaluation are temporarily behind schedule but these items do not lie on the critical path. (Author)
