EAGER: H2+ Ion Source Studies at the BEST Cyclotrons, Inc. Test Stand

这项EAGER奖励为在回旋加速器中心区域捕获和加速分子氢离子（H+2）的首次演示提供资金。这是高功率、高能回旋加速器用于基础科学和有价值的工业应用的第一步。DAEdALUS合作正在设计先进的回旋加速器，加速H+2离子产生静止衰变中微子束，以寻找中微子扇区中的电荷宇称（CP）违和。麻省理工学院和意大利国家核工业研究所（INFN-Catania, Italy）的物理学家正在与弗吉尼亚州的Best回旋加速器系统公司合作。该奖项将为大学的捐款提供资金。所需的回旋加速器在能量和功率方面必须超过世界上性能最好的回旋加速器。这一努力具有变革性——推进粒子物理学和钍基反应堆的加速器驱动技术。物理界已经把在中微子扇区寻找cp -违逆作为最高优先级。CP违背将表现为中微子与反中微子振荡的差异。当传统的中微子束遭受高系统误差时，DAEdALUS多回旋加速器设计提供了一种统计有限的替代方法。因此，这个项目有可能成为粒子物理学界的变革。该项目对回旋加速器界也具有很高的智力价值。代达罗斯回旋加速器与回旋加速器研究艺术的下一个关键步骤是一致的。在BEST回旋加速器试验台的新H+2离子源的测量，将允许首次发表高强度H+2加速的光束特性。更广泛的影响：这项工作将培养年轻的加速器科学家，并更好地将回旋加速器研究融入粒子物理社区。高功率加速器是核反应堆界感兴趣的加速器驱动系统（ADS）用于钍反应堆和锕系元素焚烧。这项工作代表了麻省理工学院和欧洲回旋加速器专家之间的合作。正如美国能源部题为“美国未来加速器”的报告所述，这项技术转让是美国的重中之重。

This EAGER award provides funding for a first demonstration of the capture and acceleration of molecular hydrogen ions (H+2) in the central region of a cyclotron. This is the first step along the path to high-power, high-energy cyclotrons for use in basic science and with valuable industrial applications. The DAEdALUS Collaboration is designing advanced cyclotrons that accelerate H+2 ions to produce decay-at-rest neutrino beams in a novel search for Charge-Parity (CP) violation in the neutrino sector. Physicists at MIT and the Istituto Nazionale di Fisica Nucleare (INFN-Catania, Italy) are collaborating with Best Cyclotron Systems Inc., of Virginia. This award will provide funding for the university contribution. The required cyclotrons must exceed the performance of the world's best performing cyclotrons in both energy and power. The effort is transformational -- advancing particle physics and accelerator driven technology for thorium-based reactors. The physics community has placed the search for CP-violation in the neutrino sector at the highest priority. CP Violation would be manifest as a difference in the oscillations of neutrinos versus antineutrinos. While conventional neutrino beams suffer from high systematic errors, the DAEdALUS multi-cyclotron design offers a statistics-limited alternative approach. Thus, this project has the potential to be transformational for the particle physics community. This project also has high intellectual merit for the cyclotron community. The DAEdALUS cyclotrons are consistent with the next crucial step in the art of cyclotron research. The measurements from a new H+2 ion source at the BEST Cyclotrons test stand, will allow the first publication of beam characteristics of high intensity H+2 acceleration. Broader Impacts:The effort will train young accelerator scientists as well as better integrate cyclotron research into the particle physics community. High power accelerators are of interest to the nuclear reactor community for the purpose of accelerator driven systems (ADS) for thorium reactors and actinide incineration. This work represents a collaboration between MIT and European cyclotron experts. This technology transfer is a high priority for the U.S., as described in the DOE report entitled Accelerators for America's Future.
