The advancement in science is closely connected to the capabilities of instrumentation. Particle accelerators are the instruments of particle physics and x-ray production. The next generations of particle accelerators are being designed to explore the frontiers of high-energy physics and for xray beams for research in biology, chemistry, physics, material science and medicine. Accelerator science research is necessary to gain greater understanding of the physical processes that can impact the performance of these accelerators and develop new techniques of particle acceleration technology. The accelerator science research will be conducted at two of the premier laboratories in the United States in accelerator science, the Cornell Laboratory for Accelerator-Based Sciences and Education (CLASSE) at Cornell University and the SLAC National Accelerator Laboratory.This award will use the Cornell Electron-Positron Storage Ring Test Accelerator (CesrTA), to examine important beam physics, such as the electron cloud effect, emittance limitations in storage rings, and the fast ion instability, for future lepton storage rings and x-ray sources. One of the key goals of the CesrTA research program is to improve our understanding of the interaction of the electron cloud with the high-energy particle beam. The electron cloud constrains many of the operational parameters of the storage ring such as beam current; bunch spacing, ring energy, and these parameters can be measured experimentally on CesrTA. Beam dynamics experiments using the CesrTA beam diagnostics capable of quantifying bunch-by-bunch and turn-by-turn beam dynamics will be used to study important lepton storage ring beam dynamics in the presence of the electron cloud. In addition, we conduct basic accelerator science research on crystal channeling at the Facility for Advanced Accelerator Experimental Tests (FACET) and the End Station A Test Beam (ESTB) facility at SLAC. Channeling is the phenomenon that arises when charged particles become trapped between the crystal planes due to the electrostatic field of the crystal ions. There is strong interest in using bent crystals as collimators and magnets for high-energy electron and positron beams and well as using crystals as generators of gamma-rays as a positron crystal undulator. The development of a crystal undulator opens the prospect of creation of novel light sources that will find their application in technology, medicine and basic sciences. Both accelerator science research projects provide Cal Poly undergraduate students research opportunities at large accelerator facilities in accelerator science. Cal Poly students will gain hands-on experience in all facets of the physics research from designing an experiment, simulating the physics, building the hardware, taking the data, analyzing the data, and publishing the results.

科学的进步与仪器的能力密切相关。粒子加速器是粒子物理和X射线产生的工具。下一代的粒子加速器旨在探索高能物理学的前沿和用于生物学，化学，物理，材料科学和医学研究的XRAE束。 加速器科学研究是必要的，以进一步了解可能影响这些加速器性能并开发粒子加速技术的新技术的物理过程。加速器科学研究将在美国的两个主要实验室进行Accelerator Science，Cornell University的基于Accelerator的科学与教育实验室（CLASSE）和SLAC国家加速器实验室和SLAC国家加速器实验室进行。存储环和快​​速离子不稳定性，用于未来的Lepton存储环和X射线源。 CESRTA研究计划的关键目标之一是提高我们对电子云与高能量颗粒光束相互作用的理解。电子云限制了存储环的许多操作参数，例如梁电流。可以在CESRTA上测量束间距，环能和这些参数。使用CESRTA束诊断的束动力学实验，能够逐束和转弯束动力学量化束束动力学，将用于研究重要的Lepton存储环束动力学。此外，我们对高级加速器实验测试（FACET）的设施中的晶体通道进行了基本的加速器科学研究，而终点站的SLAC测试梁（ESTB）设施。通道是由于晶体离子的静电场引起的，带电颗粒被困在晶体平面之间的现象。对于使用弯曲的晶体作为准直晶和磁铁，对高能电子和正电子束以及使用晶体作为伽马射线的发电机作为正电子晶体晶体不构剂，这具有浓厚的兴趣。晶体散发器的发展开放了创建新型光源的前景，这些光源将在技术，医学和基本科学中找到其应用。这两个加速器科学研究项目都为加速器科学的大加速器设施提供了Cal Poly本科生的研究机会。 Cal Poly学生将通过设计实验，模拟物理学，构建硬件，获取数据，分析数据并发布结果，从而在物理研究的所有方面获得动手经验。
