ABSTRACT:
Pulses from a particle detector and a reference-pulse generator are fed to multichannel analyzer converting the pulse amplitudes into binary signals appearing on its stage outputs, certain of these stage outputs being connected to a pair of decoders in such a way that one decoder responds to pulse amplitudes in a first group of n channels whereas the other decoder registers amplitudes in a second n-channel group divided into two halves which bracket the first group. The reference pulses are of such amplitude as to fall in the middle of the first channel group; if a measuring pulse in the detector output coincides with a reference pulse, the amplitude of the latter is either increased or decreased so as to fall mainly in one or the other half of the second group. A logic network controlled by the pulse generator energizes a forward-stepping or a backward-stepping input of a reversible pulse counter from the output of the first or the second decoder, respectively, according to whether a reference pulse occurs alone or is accompanied by a measuring pulse. When the counter reaches the limit of its counting capacity, the analyzer is cut off. The times required to attain a full count are compared for a standard sample and a test sample.
