This award is to support a group of four professors at the University of California, Santa Cruz in two areas: (1) particle accelerator research and Cherenkov ring imaging detector development, using the linear e plus e minus collider at SLAC; and (2) a particle astrophysics experiment at Los Alamos using the CYGNUS detector array. The experiment at SLAC focusses upon measurements of properties of the weak neutral boson - the Z zero - and makes use of a spectrometer built from state-of-the-art particle detection devices which this group has helped to develop and fabricate. The astrophysics experiments are concerned with observation of cosmic ray showers, particularly those due to neutral particles emanating from cosmic point sources. The investigators bring a good deal of expertise in particle physics methodology to the astrophysics enterprises and plan, for example, to make significant improvements to the angular resolution of CYGNUS to aid in identification of the sources. A number of other contributions to both performance of CYGNUS and analysis of the data from it are also expected.

该奖项旨在支持加州大学圣克鲁斯分校的四位教授在两个领域的研究：(1)粒子加速器研究和切伦科夫环成像探测器的开发，利用SLAC的线性e + e -对撞机；(2)利用CYGNUS探测器阵列在洛斯阿拉莫斯进行粒子天体物理实验。SLAC的实验重点是测量弱中性玻色子（z0）的性质，并利用由该小组帮助开发和制造的最先进的粒子探测设备构建的光谱仪。天体物理学实验涉及对宇宙射线暴的观测，特别是由宇宙点源发射的中性粒子引起的射线暴。研究人员为天体物理学企业带来了大量粒子物理学方法论方面的专业知识，并计划，例如，对CYGNUS的角度分辨率进行重大改进，以帮助识别来源。预计还将对CYGNUS的性能和来自CYGNUS的数据分析做出许多其他贡献。
