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.

技术这个项目将采取一组六名学生每年夏天（共18名学生）内的A2合作在美因茨，德国约翰内斯古滕贝格大学的MAMI加速器进行研究。 A2合作使用连续波，高达1.6 GeV的MAMI电子束，结合格拉斯哥光子标记光谱仪产生准单色光子束。 在本项目过程中使用该光子束进行的实验将通过分析中子上的单介子和多介子光生来研究核子共振谱，并通过分析单偏振和双偏振康普顿散射测量结果来提供关于核子极化率的令人兴奋的新信息。 学生将参与反应通道，分析技术和新探测器的模拟。 有些人将参与新的主动极化目标的开发和测试，包括在低温大气中测试材料和读出技术。 有些人将致力于编程FPGA芯片，用于升级的数据采集系统。 所有学生将获得获取数据的经验，监控数据质量，并在运行过程中调试任何出现的问题，从而获得现代核物理学许多领域的经验。为了确保学生群体的经验质量，调查如何最好地满足学生在国际研究经验中的教育需求，并评估该计划的好处，该方案将使用最佳实践物理教育研究为基础的技术进行审查。 学生们将在前往德国之前接受预备指导和培训，回到美国后，他们的项目将继续进行，直到他们得出结论和最终报告。 该项目的核物理和PER部分的结果将在相关期刊上发表，学生将获得全额学分。非技术性该项目旨在将一组六名学生（共十八名）带到德国的美因茨，在夏季期间在MAMI加速器的A2合作范围内开展活动。学生将有机会参与到这一合作的CA。100名物理学家，作为乔治华盛顿大学（GW）教授唐尼·奥科研究小组的一部分。 他们将参与研究核子（中子和质子）结构和动力学的硬件和软件开发。在夏季之前，学生们将在GW经历一个准备阶段，在那里他们将了解他们计划项目的物理背景，熟悉他们将使用的软件套件，并使用网络会议工具开始与他们的外国导师对话。 在美因茨约翰内斯古滕贝格大学的核物理研究所，研究人员将与IRES的学生合作开展各种项目，从主动偏振目标和新触发探测器的硬件开发和测试，到分析实验数据以寻找罕见的介子衰变，以及模拟研究以规划未来的实验。学生亦将有机会学习更广泛应用的现代科技技能，例如FPGA编程。返回美国后，IRES的学生将继续他们的研究项目，并将在一个特别的研讨会上发表最后报告和演讲，以展示学生们。工作 还将鼓励学生申请CEU奖学金，以便在更广泛的范围内展示他们的工作。 在整个IRES计划的过程中，每个学生的教育效益和进步将由GW的Teodorescu教授进行监测，包括入学，中期和退出面试。 Professors Albercoe，Downie和Teodorescu将共同努力，通过正在进行的IRES计划的研究，制定一个指导学生进行国际研究的教育框架，这项工作的结果将发表在适当的物理教育研究期刊上。
