Use of multichannel plate detectors has considerably extended the experimental techniques in atomic physics. In this context, a coincidence circuitry able to determine 64simultaneouscoincidence spectra is described. Use of fast electronic devices and separated amplifiers allows a high counting rate capability (5times;105events per second) with a time resolution of 3.1 ns. UV photonhyphen;scattered particle coincidence in Hendash;He collisions is given as an example of the application of the present apparatus.
