One of the major intellectual achievements of the 20th century was the development of the Standard Model (SM) of particle physics. This model succeeded in classifying all of the elementary particles known at the time into a hierarchy of groups having similar quantum properties. The validity of this model to date was recently confirmed by the discovery of the Higgs boson at the Large Hadron Collider at CERN. However, the Standard Model as it currently exists leaves open many questions about the universe, including such fundamental questions as to why the Higgs mass has the value it has. One technique for exploring physics Beyond the Standard Model (BSM) is in making precision measurements of SM model atomic parameters such as the electric dipole moment (EDM) of the neutron. This award will develop the accelerator technology necessary for such a precision measurement of the neutron EDM. This project is to explore essential tools for exploration of physics beyond Standard model of particle physics. Tools for this exploration include a neutron beam storage ring, polarized proton beams and high power beams. Besides the basic physics, high power beams can be important to "nuclear waste" incineration, which can be important to national security.This award will allow the study of synchro-betatron coupling of polarized beams relevant to the measurement of EDM, continuing exploration of a neutron beam storage ring, and envelope dynamics of high power proton accelerators. The group will study spin dynamics and synchrotron-betatron coupling of all electric rings that are relevant to polarized beams and will continue to study the neutron beam storage ring. The longitudinal focusing of longitudinal phase space has been explored. The transverse dynamics in using periodic quadrupole and sextupole magnets will be explored to fulfill the initial design of a storage ring. TEST beam experiments will be carried out to test numerical simulations for high power beams.

20世纪的主要智力成就之一是粒子物理标准模型(SM)的发展。这个模型成功地将当时已知的所有基本粒子归入具有相似量子性质的群组的层次结构中。最近在欧洲核子研究中心的大型强子对撞机上发现的希格斯玻色子证实了这个模型到目前为止的有效性。然而，目前存在的标准模型留下了许多关于宇宙的问题，包括为什么希格斯质量具有它的价值这样的基本问题。探索超越标准模型(BSM)的物理的一种技术是精确测量SM模型的原子参数，如中子的电偶极矩(EDM)。该奖项将开发对中子电火花加工进行如此精确测量所需的加速器技术。这个项目是为了探索超越粒子物理标准模型的物理探索的基本工具。这次探测的工具包括中子束储存环、极化质子束和高功率束。除了基本的物理原理，高功率束流对“核废料”焚烧也很重要，这可能对国家安全很重要。这项奖励将允许研究与电火花加工测量相关的偏振束流的同步-Betatron耦合，继续探索中子束存储环，以及高功率质子加速器的包络动力学。该小组将研究与偏振光束相关的所有电环的自旋动力学和同步加速器-倍电子耦合，并将继续研究中子束存储环。对纵向相空间的纵向聚焦进行了探讨。为了完成储存环的初步设计，将探索使用周期四极磁体和六极磁体时的横向动力学。将进行试验束实验，以检验高功率束的数值模拟。
