Abstract

The Sudbury Neutrino Observatory (SNO) is a second generation solar neutrino water Cherenkov detector using 1000 tonnes of D/sub 2/O viewed by almost 10000 20 cm photomultiplier tubes. The observatory, located 6800 ' below ground in INCO Ltd's Creighton mine near Sudbury Ontario, recently began full time operation. The SNO electronics provides deadtimeless sub-ns time and 0.1-1000 photoelectrons (pe) of charge measurement. While the solar neutrino event rate is low, the electronics must handle backgrounds in excess of 1 kHz and bursts in excess of 1 MHz. The integrated trigger system handles multiple independent triggers via 10000:1 analog sums. The electronics use three full custom integrated circuits plus standard commercial chips. There are 14 different printed circuit boards mounted in custom crates and racks. The DAQ interface is VME compatible.

萨德伯里中微子天文台的电子性能

萨德伯里中微子天文台(SNO)是第二代太阳中微子水切伦科夫探测器，使用近10000个20厘米光电倍增管观测1000吨D/sub 2/O。该观测站位于INCO公司位于安大略省萨德伯里附近的Creighton矿山地下6800英尺处，最近开始全职运营。SNO电子学提供无死区亚ns时间和0.1-1000个光电子(pe)的电荷测量。虽然太阳中微子事件率很低，但电子设备必须处理超过1khz的背景和超过1mhz的爆发。集成触发器系统通过10000:1模拟和处理多个独立触发器。电子产品使用三个完整的定制集成电路和标准的商业芯片。有14种不同的印刷电路板安装在定制的板条箱和机架上。DAQ接口是VME兼容的。
