title: Simple low-cost digital events analyzer.
abstract: We present the design and applications of a simple and very low-cost digital events analyzer, suitable for use in a student laboratory as well as in research applications. The pulse analyzer can perform five functions: sampling measurement; pulse interval distribution measurement; simple triggered multichannel scaling; scaled triggered multichannel scaling; and auto- and cross-correlation function measurement. The memory capacity is limited to 100 channels with 11 bits or more word length. The basic cycle time of the analyzer is 500 ns as limited by the speed of MOS circuit used. We demonstrate the utility of it with counting statistics experiments of radiations from radioactive decay, neutron time of flight analysis, and also the photon correlations measurements of light scattered from particles in fluids.
