French Electronics for G0

Four of the eight detector octants will be instrumented with electronics built by the French institutions in the G0 collaboration. Initially two approaches were explored, one by the Grenoble group and the other by the Orsay group.

The Grenoble Electronics plan followed closely the North American scheme, using, however, a more highly integrated approach. Custom mean-timer and scaler chips were developed. All electronics for a number of detector channels were to implemented on a single VME board. Separate boards were to be designed for the forward and the backward angle modes.

The Orsay Electronics plan employs Digital Signal Processor (DSP) technology as well as custom discriminators, mean-timers and TDCs to provide flexible and highly integrated front-end processing. Ultimately it was this approach that was chosen by the collaboration.
