Magnetostrictive delay lines for outer digital processing systems

Abstract

Utilization of magnetostrictive delay-line storage to discharge the communication channels between the central computer and outer analog-to-digital converters is discussed. Examples are given of the utilization of two synchronized delay lines, each having a 500 kHz clock frequency and a 1024-bits capacity, in the pulse height analyser, using continuous storing of flowing spectra simultaneously with the output of the preceding amplitude spectrum. In the same analyser the spectrum area as well as the areas of its four preset regions are computed simultaneously with the spectrum storing. Four delay lines, each having a 2 MHz clock rate and a 2048-bits capacity, are used in the 512-channel pulse height analyser. Eight delay lines of the same type are used in the 2048-channel time selector, its dead time being equal to the (0.5; 1; 4 μs) time channel band width. Five delay lines, each having a 2 MHz clock frequency and a 32-bits capacity, are used in the four-dimensional non-integrating pulse height analysers as time-to-binary code converters and as digital integrators of the peak and zero stabilizers of each analog-to-digital converter.
