TechnicalThis project will take a group of six students each summer (eighteen students in total) to perform research within the A2 collaboration at the MAMI accelerator of the Johannes Gutenberg University in Mainz, Germany. The A2 collaboration uses the continuous wave, up to 1.6 GeV MAMI electron beam, in combination with the Glasgow Photon Tagging Spectrometer to produce a quasi-monochromatic photon beam. The experiments performed with this photon beam in the course of this project will investigate the nucleon resonance spectrum by analyzing single and multiple meson photoproduction on the neutron and provide exciting new information on the nucleon polarizabilities through analyses of single and doubly polarized Compton Scattering measurements. The students will be involved in the simulation of reaction channels, analysis techniques and new detectors. Some will be involved in the development and tests of the new Active Polarized Target, involving tests of material and read-out techniques in a cryogenic atmosphere. Some will work on programming FPGA chips for uses in an upgraded data acquisition system. All students will gain experience taking data, monitoring data quality as it is collected and debugging any problems which occur during running, thereby gaining experience in many of the areas of modern nuclear physics.To ensure the quality of the experience for the student cohort, to investigate how best to serve the educational needs of students during international research experience and to evaluate the benefits of the program, the program will be examined using best-practice physics education research-based techniques. The students will receive preparatory instruction and training before leaving for Germany and upon return to the US, their projects will continue until they reach conclusion and final reporting. The results of the nuclear physics and PER components of the program will be published in the relevant journals, with the students receiving full credit, where appropriate.Non-TechnicalThis project is designed to take a group of six students (eighteen in total) to Mainz, Germany to work on activities within the A2 collaboration at the MAMI accelerator during the summer. The students will have the opportunity to become involved in this collaboration of ca. 100 physicists, as part of the research groups of Professors Downie & Briscoe of the George Washington University (GW). They will be involved in hardware and software development for the investigation of the structure and dynamics of the nucleon (neutrons and protons). Before the summer, the students will undergo a preparatory phase at GW, where they will learn about the physics background of their planned project, become familiar with the software suites they will use, and begin dialogue with their foreign supervisor using web-conferencing tools. At the Institut fuer Kernphysik, of the Johnannes Gutenberg university, Mainz, researchers will work with the IRES students on a variety of projects from hardware development and tests for the Active Polarized Target and new trigger detectors, to analysis of experimental data to search for rare meson decays, and simulation studies to plan for future experiments. The students will also have the chance to acquire modern technological skills of wider application, such as FPGA programming.Upon their return to the US, the IRES cohort will continue their research projects, producing a final report and a presentation which will take place at a special symposium to showcase the students? work. The students will also be encouraged to apply for the CEU fellowships to present their work in a wider circle. Throughout the course of the IRES program, the educational benefit to and progress of each student will be monitored by Prof. Teodorescu of GW, with entrance, mid-term, and exit interviews. Professors Briscoe, Downie and Teodorescu will work together to formulate an educational framework for mentoring students in international research through the study of the ongoing IRES program, and the results of this effort will be published in appropriate physics education research journals.

TechnicalThis Project将每年夏天（总共十八名学生）组成的六名学生（总共十八名学生）在德国Mainz的Johannes Gutenberg University的Mami Accelerator的A2合作中进行研究。 A2协作使用连续波，最高1.6 GEV MAMI电子束，并结合Glasgow光子标记光谱仪，产生准单色光子光束。 在该项目过程中使用该光子束执行的实验将通过分析中子上的单个和多个介子光增生性来研究核子共振光谱，并通过分析单个和双层极化的综合群散射测量值分析核素极化能力的令人兴奋的新信息。 学生将参与反应渠道，分析技术和新探测器的模拟。 一些将参与新的主动偏振靶标的开发和测试，涉及在低温气氛中进行材料和读出技术的测试。 有些将致力于编程FPGA芯片，以用于升级的数据采集系统。 所有学生都将获得获取数据的经验，监控数据质量并调试跑步过程中发生的任何问题，从而在现代核物理学的许多领域中获得经验。确保学生队列的经验质量，以调查如何最好地满足学生在国际研究经验期间学生的教育需求，并利用该计划的益处，以使用最佳效果教育研究来进行研究。 学生将在离开德国之前并返回美国之前接受预备指导和培训，他们的项目将继续，直到他们得出结论和最终报告。 核物理学的结果和该计划的每个组成部分将在相关期刊上发布，并且在适当的情况下，学生获得了全部信贷。Non-Technicalthisthis项目旨在将六名学生（总共十八个）（总共十八个）（总共十八个）带到德国，在夏季在Mami Accelerator进行A2协作中的活动。学生将有机会参与CA的这一合作。 100位物理学家，作为乔治华盛顿大学（GW）教授Downie＆Briscoe的研究小组的一部分。 他们将参与硬件和软件开发，以研究核子（中子和质子）的结构和动力学。在夏季之前，学生将在GW进行准备阶段，在那里他们将了解其计划项目的物理背景，熟悉他们将使用的软件套件，并开始使用网络会议工具与外国主管进行对话。 在Mainz Johnannes Gutenberg大学的Institut Fuer Kernphysik上，研究人员将与IRES学生合作进行各种项目，从硬件开发和对主动两极化目标和新的触发探测器进行测试，到分析实验数据到实验数据到寻找稀有中子衰减的研究，以及寻找未来实验的模拟研究。学生还将有机会获得更广泛应用的现代技术技能，例如FPGA编程。工作。 还将鼓励学生申请CEU奖学金，以更广泛的圈子介绍他们的作品。 在IRES计划的整个过程中，GW的Teodorescu教授将对每个学生的教育收益和进步进行监控，并进行入口，中期和退出访谈。 Briscoe，Downie和Teodorescu教授将通过研究正在进行的IRES计划的研究来建立一个教育框架，以指导学生在国际研究中，并将在适当的物理教育研究期刊上发表这项工作的结果。
