PROJECT LIGHTNING
Abstract
Work was continued in cryogenics and associated machine organization devoted to evaluating the feasibility of a computer system capable of performing basic logic operations at a rate of 1000 mc. It was concluded that substantial improvement in the efficiency of a kilomegacycle cryotronic machine can be obtained by reducing the planar dimensions of the circuits and using a substrate having high thermal conductivity. Efforts were made to find substrates which can be used for circuits and which will alleviate the heat problem by increasing the thermal conductivity to the bath. A first set of results was obtained in the multiplexing study and preliminary data on the effect of queue length are reported. A plan to design and construct a high-speed addressable memory was prepared. The modifications of the cryotron network simulator resulted in simulation results that agreed with experimental results for slow crossed-film cryotron circuits.
