Three single crystal faceplates were to be integrated into Cathode Ray Tube CRT envelopes with the intent of evaluating the light output from CeYAG Green, modified CeGD, YAG Orange, CEBEL Blue. These CRTs were to be mounted in the projection test bed developed under Contract N61339-90-C-0047 and furnished G.F.P. to Trident International, Inc. for use and delivery during this contract. Three 3 inch diameter CeYAG faceplates were supplied as GFP from previous contract N61339-90-C-0047. One of these three was to be used for construction of a CRT, the remaining two were to be used for coating test. During the processing of the CRTs one of the crystals was destroyed. The other two single crystal faceplates were incorporated in test CRTs. An additional CeGd, YAG Red shifted green faceplate of 1.5 inches diameter and two CeBEL Blue crystals of 0.75 inch diameter were obtained from Allied Signal, Inc, by Trident. Investigations were made to provide optimum optical coupling of the CRT light output into a projection lens. Index matching heat dissipation fluids were used. A wide angle lens was selected and supplied by the contractor.
