技术摘要：该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。我们建议获取高电荷离子（HCI）光束线，用于探索HCI-材料的相互作用。hci -固体碰撞中存在的固有高能量密度，其中高度电离原子的可重复量子力学状态在原子长度尺度上将能量转移到固体中，给出的辐照值（~1014 W/cm2）可与petawatt激光器（~7x1011 W/cm2）相媲美，并且可以比激光更容易获得和保持。理解控制HCI如何将这种能量传递到目标的物理机制是材料研究中将要解决的主要和开放问题。有了这个仪器，我们将能够创建一个选定的电荷状态的hci，并将它们撞击到定义明确的目标上，其中二次电子、x射线和质量损失传感将用于实时分析和精确定时（通过x射线去激发）撞击事件。在此过程中，我们将探索基本原子物理（x射线发射，里德伯原子形成等）和能量耗散之间的复杂相互作用，这是hci材料相互作用的定义特征。通过该光束线获得的结果将直接应用于hci在电子设备加工中的使用，以及聚变反应堆壁候选材料的评估，hci在天体物理相关离子目标撞击条件中的作用，以及电子设备和材料的加速航天准备测试。该仪器将被安置在克莱姆森大学的中心校区，将由一名训练有素的技术人员操作，并将通过工程与科学学院和大学的承诺和联合支持来维护。核心调查人员和管理团队将利用此次收购，通过校园内建立的项目以及我们与南卡罗来纳州立大学的现有联系，加强我们对女性和少数族裔的外展项目。非技术总结：该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。我们建议收购高电荷离子（HCI）光束线，用于克莱姆森大学的跨学科材料研究和教育。高电荷离子是一种被剥夺了大部分电子的原子，它们是独一无二的，因为它们具有高能量密度，可以导致在材料实验室环境中通常不会遇到的新型hci -固体相互作用。我们此次收购的目标是探索控制HCI如何将能量传递到目标的物理机制，并将这些知识应用于HCI作为电子材料制造加工工具的开发。此外，核聚变反应堆（清洁能源生产的候选技术）以及空间环境中固有的hci的存在，使得此次收购成为在实验室环境中再现这些条件的主要工具。作为研究实验室和研究HCI与材料相互作用的用户设施，这条光束线将为众多研究人员打开新的大门，并鼓励他们探索这种独特的物质形式。此次收购将无低温技术用于生产hci，确保其作为低成本、单操作员光束线的功能，对用户和合作伙伴的参与具有低门槛。该仪器将被安置在克莱姆森大学的中心校区，将由一名训练有素的技术人员操作，并将通过工程与科学学院和大学的承诺和联合支持来维护。核心调查人员和管理团队将利用此次收购，通过校园内建立的项目以及我们与南卡罗来纳州立大学的现有联系，加强我们对女性和少数族裔的外展项目。

0960100SosolikClemson U.Technical Summary: This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).We propose the acquisition of a highly charged ion (HCI) beamline dedicated to the exploration of HCI-materials interactions. The intrinsic high energy density present in an HCI-solid impact, where a reproducible quantum mechanical state of a highly ionized atom transfers energy into a solid at atomic length scales, gives irradiance values (~1014 W/cm2) that rival those achievable with petawatt lasers (~7x1011 W/cm2) and that can be obtained and maintained more easily than a laser. Understanding the physical mechanisms that control how an HCI can deliver this energy to a target is the primary and open question of materials research that will be addressed. With this instrumentation we will be able to create HCIs of a selected charge state and impact them onto well-defined targets where secondary electron, X-ray, and mass loss sensing will be used for real-time analysis and precisely timed clocking (via X-ray deexcitation) of impact events. In doing so, we will probe the complex interplay between fundamental atomic physics (X-ray emissions, Rydberg atom formation, etc.) and energy dissipation that is the defining characteristic of HCI-materials interactions. Results obtained with this beamline will be directly applied to the use of HCIs in electronic device processing as well as the evaluation of candidate materials for fusion reactor walls, the role of HCIs in astrophysically relevant ion-target impact conditions, and the accelerated spaceflight-readiness testing of electronics devices and materials. This instrumentation will be housed on the central campus of Clemson University, will be operated by a trained staff technician, and will be maintained through the committed and combined support of the College of Engineering and Science and the university. The core investigators and management team will utilize this acquisition to enhance our outreach programs to women and minorities through established programs on campus and through our existing connection with South Carolina State University.Non-Technical Summary: This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).We propose the acquisition of a highly charged ion (HCI) beamline for interdisciplinary materials research and education at Clemson University. Highly charged ions, which are atoms stripped of a large fraction of their electrons, are unique as they possess a high energy density that can lead to novel HCI-solid interactions not typically encountered in a materials laboratory environment. Our goals with this acquisition are to explore the physical mechanisms that control how a HCI can deliver energy to a target and apply that knowledge to the development of HCIs as a processing tool for electronic materials fabrication. In addition, the inherent presence of HCIs in fusion reactors, a candidate technology for clean energy production, as well as in the space environment makes this acquisition a prime tool for reproducing these conditions in a laboratory setting. Operating as a research laboratory and user facility for the study of HCI interactions with materials, this beamline will open new doors to a multitude of researchers and encourage their explorations into this unique form of matter. The incorporation of cryogen-free technologies for the production of HCIs into this proposed acquisition ensures that it will function as a low cost, single-operator beamline that has a low threshold for user and collaborator participation. This instrumentation will be housed on the central campus of Clemson University, will be operated by a trained staff technician, and will be maintained through the committed and combined support of the College of Engineering and Science and the university. The core investigators and management team will utilize this acquisition to enhance our outreach programs to women and minorities through established programs on campus and through our existing connection with South Carolina State University.
