Abstract

Probably the most critical component in the Williams Memory System is the storage tube itself. It was originally supposed that ordinary cathode ray tubes, designed for use in oscilloscopes, would suffice for the storage element in this type of electrostatic memory but it soon became apparent that these tubes had two serious defects. First, they had impurities on the storage surface, and₂ second, the focus of the electron beam was not sharp enough to allow repetitive consultation of one storage location without disturbing the surrounding information.

These defects are opposite in nature so that the circuit parameter change that improves one of these conditions, aggravates the other. Thus, if the acceleration voltage is increased, the focus improves but the impurities become more troublesome.

Small-sized flat-tip CNT emitters for miniaturized x-ray tubes
Special issue on Micro/Nanostructured Arrays: Fabrication, Applications and Devices

Small tip-type CNT emitters with the diameter of 0.8 mm were fabricated for miniaturized X-ray tubes. The CNT emitters were prepared by dropping CNTs and silver nanoparticles on a flat surface of a W metal tip followed by annealing at 800°C for 2h under ...
