IRES -Experimental Nuclear Physics at the Mainz Microtron

该项目每年夏天将邀请六名学生（共十八名学生）在德国美因茨约翰内斯古腾堡大学的MAMI加速器中进行A2合作研究。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。本项目的实验将通过分析中子上的单和多介子光产生来研究核子共振谱，并通过分析单和双极化康普顿散射测量来提供有关核子极化的令人兴奋的新信息。学生将参与反应通道的模拟，分析技术和新的探测器。一些人将参与开发和测试新的有源极化目标，包括在低温大气中测试材料和读出技术。一些人将致力于编程FPGA芯片，用于升级的数据采集系统。所有学生都将获得采集数据、监测数据质量以及调试运行过程中出现的任何问题的经验，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体验质量，为了调查如何在国际研究经历中最好地满足学生的教育需求，为了评估项目的好处，该项目将使用最佳实践的物理教育研究技术进行检查。学生将在前往德国前接受前期指导和培训，并在返回美国后继续进行项目，直至结题并完成最终报告。该计划的核物理和PER部分的结果将在相关期刊上发表，学生将在适当的情况下获得全额学分。这个项目的目的是带一组6名学生（总共18人）到德国美因茨，在MAMI加速器的A2合作活动中工作。学生们将有机会作为乔治华盛顿大学（GW） Downie & Briscoe教授研究小组的一部分，参与大约100名物理学家的合作。他们将参与核子（中子和质子）结构和动力学研究的硬件和软件开发。在暑期之前，学生们将在乔治华盛顿大学经历一个准备阶段，在那里他们将学习他们计划项目的物理背景，熟悉他们将要使用的软件套件，并开始使用网络会议工具与他们的外国导师进行对话。在美因茨约翰内斯·古腾堡大学的Kernphysik研究所，研究人员将与IRES的学生一起进行各种各样的项目，从硬件开发和有源极化目标和新触发探测器的测试，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。学生也将有机会获得更广泛应用的现代技术技能，如FPGA编程。在他们返回美国后，IRES团队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终报告和演讲，以展示学生们的研究成果。工作。我们也鼓励学生申请中欧大学奖学金，以便在更大的范围内展示他们的作品。在整个IRES项目的过程中，GW的Teodorescu教授将通过入学、期中和毕业面试来监督每个学生的教育效益和进步。布里斯科、唐尼和特奥多雷斯库教授将共同制定一个教育框架，通过对正在进行的IRES项目的研究，指导学生进行国际研究，这项工作的结果将发表在适当的物理教育研究期刊上。

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.
