This research program is directed toward the development of markedly improved high performance displays, designed to enhance diagnosis in digital mammography. The activities of the second year centered on the delivery and first use of the instrumentation for the experimental investigation of the novel cathodoluminescent materials. 1 The demountable display tube and its associated vacuum system and electronic control was delivered, installed and used for the first time. It permits investigation of samples of the novel cathodoluminescent materials and their respective substrates with respect to characteristic display performance measures. 2 Three CsI samples were ordered from the University of California at Berkeley delivered and evaluated in the demountable display tube. 3 A theoretical study was done and found that the combination of cathodo-luminescence and electro-luminescence in the same display tube can lead to displays with higher brightness than conventional displays. The result of this study is presented in the Appendix of this report as a proposal to be submitted to NIH. 4 Based on the fact that the work to be done in this project has not been completed by any means, it is requested to extend this project without cost for one year.
