布鲁克斯-国际研究奖学金计划使美国科学家和工程师能够在国外进行三到二十四个月的研究。该计划的奖项提供了联合研究的机会，并利用国外独特或互补的设施、专业知识和实验条件。该奖项将支持Nathan R.Brooks博士与瑞士日内瓦CERN的Luca Bottura博士合作的为期22个月的研究奖学金。磁性测量系统的设计、实现和性能方面的障碍对磁性应用和应用超导领域非常感兴趣。具体地说，需要更快、更准确地测量磁场。在某些应用中，旋转线圈系统是最精确的现场测量方法之一。但是，由于增加了机械旋转的复杂性，该方法并不是最快的。他建议改进以前的旋转线圈测量系统。基本目标将是在不降低精度的情况下提高这些测量的速度。这对于测量快速变化的领域非常重要。作为实现这一目标的一种方法，调查将需要测量仪器和必要的机电系统。磁场研究中最突出的领域之一是将其用于粒子加速器进行物理研究。欧洲核子研究中心为其下一个也是最伟大的加速器--大型强子对撞机(LHC)启动了一项强有力的研究和开发计划。大型强子对撞机超导磁体需要在欧洲核子研究中心进行广泛的测试，以在调试之前验证其性能。主要的测试之一是磁场质量测试，该测试使用旋转线圈测量系统。此外，由于大型强子对撞机要求严格的磁铁性能，这些磁铁必须以高精度运行。因此，Luca Bottura博士已经开始了参考磁铁系统(RMS)的概念设计，以帮助优化控制大型强子对撞机。该系统需要一种新的和改进的旋转线圈系统。该项目将是对欧洲核子研究中心设施的重大改进，新的旋转线圈系统将是加速器磁体测量的下一步发展。通过提供关于加速器主题的论文和教程的CERN加速器学校，其他机构将利用我们的工作来推进他们的系统。加速器磁体性能的这些改进对于这些设施的粒子物理实验是必要的，以便利用科学为社会做出更好的贡献。

0502410BrooksThe International Research Fellowship Program enables U.S. scientists and engineers to conduct three to twenty-four months of research abroad. The program's awards provide opportunities for joint research, and the use of unique or complementary facilities, expertise and experimental conditions abroad.This award will support a twenty-two-month research fellowship by Dr. Nathan R. Brooks to work with Dr. Luca Bottura at CERN in Geneva, Switzerland.Obstacles in design, realization, and performance of a magnetic measurement system are of great interest in areas of magnetic applications and applied superconductivity. Specifically, the need to measure magnetic fields faster and more accurately is a necessity. Rotating coil systems are one of the most accurate methods of field measurement in certain applications. But, due to the added complexity of mechanical rotation, the method is not the speediest. He proposes to improve upon previous rotating coil measurements systems. The fundamental objective will be to increase the speed at which these measurements can be made, without degrading the accuracy. This is important for measuring fields that change rapidly. As an approach to achieving this objective, the investigation will entail both the measurement instrumentation and the necessary electromechanical system. One of the most prominent areas of research in magnetic fields is their use in particle accelerators for physics research. CERN has started a vigorous research and development program for its next and greatest accelerator, the Large Hadron Collider (LHC). The LHC superconducting magnets require extensive testing at CERN to verify their performance before commissioning. One of the main tests is the magnetic field quality test, for which a rotating coil measurement system is utilized. Also, due to the stringent magnet performance required for the LHC, these magnets have to be operated with high accuracy. Therefore, Dr. Luca Bottura hasstarted a conceptual design of a Reference Magnet System (RMS) to aid in optimally controlling the LHC. This system requires a new and improved rotating coil system. This project will be a major enhancement of the facilities at CERN and the new rotating coil system will be the next evolutionary step in accelerator magnet measurement. By means of the CERN accelerator school, which provides papers and tutorials on accelerator topics, other institutions will leverage our work to advance their systems. These improvements in accelerator magnet performance arenecessary for the particle physic experiments at these facilities, so that science can be exploited for the betterment of society.
