Abstract

The Sudbury Neutrino Observatory (SNO) is a second generation real time solar neutrino water Cherenkov detector using 1,000 Tonnes of D2O viewed by almost 10,000 Photomultiplier tubes 20cm in diameter. The electronics chain is required to provide deadtimeless sub-nanosecond time and charge measurement for Photomultiplier pulses in the range of 1 – 1000 photo electrons. While the solar neutrino event rate is very low, the electronics chain must handle background rates in excess of 1 kHz and burst rates in excess of 1 MHz. The electronics chain is implemented using three full custom integrated circuits and commercial ADCs, memory, and logic. The DAQ interface is VME compatible. We will briefly describe the SNO detector and then concentrate on the design of the electronic system including novel features of the DAQ and trigger paths.
