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

这项急切的奖项为首次演示分子氢离子(H+2)在回旋加速器中心区域的捕获和加速提供了资金。这是迈向高功率、高能回旋加速器的第一步，用于基础科学和有价值的工业应用。Daedalus合作正在设计先进的回旋加速器，以加速H+2离子产生静态衰变的中微子束，这是一种在中微子领域寻找电荷宇称(CP)破坏的新方法。麻省理工学院和费西卡核研究所(INFN-卡塔尼亚，意大利)的物理学家正在与弗吉尼亚州的贝斯特回旋加速器系统公司合作。这一奖项将为大学的贡献提供资金。所需的回旋加速器必须在能量和功率方面超过世界上性能最好的回旋加速器的性能。这一努力是变革性的--推动了基于钍的反应堆的粒子物理和加速器驱动技术的发展。物理学界已经把寻找中微子部门的CP破坏放在了最优先的位置。CP破坏将表现为中微子和反中微子振荡的不同。虽然传统的中微子束遭受着很高的系统误差，但代达罗斯多回旋加速器设计提供了一种统计有限的替代方法。因此，这个项目有可能为粒子物理界带来变革。这个项目对回旋加速器社区也有很高的智力价值。代达罗斯回旋加速器与回旋加速器研究的下一个关键步骤是一致的。在最好的回旋加速器试验台上，来自一个新的H+2离子源的测量将允许首次公布高强度H+2加速的束流特性。更广泛的影响：这一努力将培训年轻的加速器科学家，并将回旋加速器研究更好地整合到粒子物理学领域。高功率加速器是核反应堆领域的研究热点，可用于钍反应堆的加速器驱动系统(ADS)，也可用于氚的焚烧。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《美国未来的加速器》的报告中所描述的那样，这种技术转让对美国来说是高度优先的。

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.
