This action provides funds for continued research in elementary particle physics by a group at the Santa Cruz Institute of Particle Physics, University of California, Santa Cruz. The group will construct and operate major portions of a Cerenkov Ring Imaging Detector for incorporation into the Large Detector (SLD) at the Stanford Linear Accelerator Center. This research will exploit the advances in instrumental techniques in such detectors made by this and other groups over the last three years. It will culminate in the full utilization of the Stanford Linear Accelerator Center linear collider's capabilities to explore the physics of the Zo particle and of other physical processes extant at these energies. In particular, this device adds to the SLD the capability to separate emerging particles by type (mass) over virtually the entire spectrum of energies expected. This in turn allows deeper analysis of the physics which dictated that such particles would result from electron-positron annihilation. It is believed that a modern detector without such capability would not be competitive in the physics of this energy range.

这一行动为加州大学圣克鲁斯分校圣克鲁斯粒子物理研究所的一个小组继续进行基本粒子物理研究提供了资金。该团队将建造和运营切伦科夫环成像探测器的主要部分，以整合到斯坦福直线加速器中心的大型探测器(SLD)中。这项研究将利用该小组和其他小组在过去三年中在这类探测器中所取得的仪器技术的进步。它的最终结果是充分利用斯坦福直线加速器中心的直线对撞机的能力来探索ZO粒子的物理和在这些能量下存在的其他物理过程。特别是，该设备为SLD增加了在几乎整个预期能量谱上按类型(质量)分离浮现粒子的能力。这反过来又允许对物理进行更深入的分析，该物理决定了这种粒子将是电子-正电子湮灭的结果。人们认为，没有这种能力的现代探测器在这个能量范围的物理上是没有竞争力的。
