The Sudbury Neutrino Observatory (SNO) is a solar neutrino detector located in INCO's Creighton Nickel Mine near Sudbury, Ontario.  In 2002 SNO solved the longstanding "solar neutrino problem" by demonstrating that electron neutrinos produced inside the Sun change into other flavours of neutrino on their way to Earth.  This discovery requires neutrinos to have non-zero mass and new properties.  The UBC/TRIUMF SNO group is closely involved in all aspects of the physics analysis of SNO's data, especially day-night analyses, searches for periodic variations in the solar neutrino flux, atmospheric neutrino analysis, and precise measurement of the solar neutrino mixing parameters.  This grant supports the activities of the UBC/TRIUMF group over the final phase of the SNO experiment.

萨德伯里中微子观测站 (SNO) 是一个太阳中微子探测器，位于安大略省萨德伯里附近的 INCO 克雷顿镍矿。  2002年，SNO通过证明太阳内部产生的电子中微子在到达地球的途中转变为其他类型的中微子，解决了长期存在的“太阳中微子问题”。  这一发现要求中微子具有非零质量和新特性。  UBC/TRIUMF SNO 小组密切参与 SNO 数据物理分析的各个方面，特别是昼夜分析、搜索太阳中微子通量的周期性变化、大气中微子分析以及太阳中微子混合参数的精确测量。  这笔赠款支持 UBC/TRIUMF 小组在 SNO 实验最后阶段的活动。
