This grant funds the development and construction of a silicon strip detector array for experiments with fast radioactive nuclear beams. Such beams will soon be available, albeit with low intensities, at radioactive beam facilities and will allow important investigations in the areas of nuclear structure and nuclear astrophysics. To be useful at these facilities, detection arrays must cover most if not all of the interesting solid angle. This array does so with high resolution, and low cost by utilizing advanced high density readout electronics. Once constructed, the array will be a powerful research instrument for determining the structure of extremely neutron-rich or neutron-deficient nuclei. It will also enable the measurement of many nuclear properties that are relevant to the nucleosynthesis of the elements within stars, novae and supernovae. This array will provide significant new capabilities for performing radioactive beam experiments; the development of such capabilities was identified as the highest priority new initiative in the 1995 Long Range Plan for Nuclear Physics.

这笔赠款资助了硅带探测器阵列的开发和建造，用于快速放射性核束实验。 尽管强度较低，但这种束很快就会在放射性束设施中使用，并将允许在核结构和核天体物理学领域进行重要研究。为了在这些设施中发挥作用，检测阵列必须覆盖大部分（如果不是全部）感兴趣的立体角。该阵列利用先进的高密度读出电子器件，以高分辨率和低成本实现这一点。一旦建成，该阵列将成为一种强大的研究仪器，用于确定极度富中子或极度缺乏中子的原子核的结构。它还将能够测量与恒星、新星和超新星内元素核合成相关的许多核特性。 该阵列将为进行放射性束实验提供重要的新功能； 1995 年核物理长期计划将这种能力的发展确定为最优先的新举措。
