The objective of the contract is to conduct a research and development program leading to the fabrication, testing, and delivery of a binary-addressable scan-converter storage tube. The tube is to be capable of simultaneous write and nondestructive read operation at video frequency up to 10 megahertz. Experiments were performed for producing the hole-array, consisting of 512 x 512 holes, 0.001-inch in diameter on 0.003-inch centers, in silicon wafers. Both photoanodic etching and laser drilling were explored. The designs for the contact strip arrangements on the disks were finalized, and the various fixtures were manufactured for control of photo-resist exposure and for securing registry of the hole-arrays of the sequence of digitizer-disks.
