Fast triggering device based on parallel memory look up tubes to operate under high multiplicity of detected events. Part 2

A device for fast triggering based on parallel memory look up tables is described. It is designed to be used with three tracking detectors (hodoscopes) consisting of 32 elements. The device can analyze up to three coordinates in each hodoscope during the time no more than 160 ns. An integrated circuit K500PY415 as the memory element is used. The first part of the paper describes electronics and software for its testing. The second part describes the design of the hodoscopes, service software and look up table contents calculations and experimental results. 3 refs.; 8 figs.; 1 tab
