RESEARCH ON LOW TEMPERATURE COMPUTING ELEMENTS
Abstract
Research was carried out in 7 different areas. These include a solution of the London Equations for thin films, development of evaporation techniques, studies of polymer insulating films, fabrication and tests of thin film flip-flops, deposition of metal films by electron bombardment, design of a large circuit evaporator, and further development of the associative memory design. The evaporation studies led to a considerable improvement in the reproducibility of cryotrons. The polymer insulating film is now used in all superconducting devices fabricated in the program. A number of superconducting flip-flops were fabricated, the most recent of which has a reversal time of 35 nanoseconds. The considerable improvement in reproducibility of cryotrons and polymer insulation made it feasible to proceed to develop equipment for production of dense circuits of up to 1000 cryotrons on 10 sq in. of substrate. A large circuit evaporator with this capability was designed. Fabrication and tests of various high density masks suitable for producing 100 cryotrons/sq in. are currently under way. (Author)
