The R&D described in the award Superconducting RF (SRF) Development for the Project X Neutrino Beam to DUSEL is viewed as highly relevant, and can be is of national and international importance. The science that could be enabled by this R&D includes programs at DUSEL, the proposed Deep Underground Science and Engineering Laboratory in South Dakota.Project X is a collection of experiments proposed to compose a future Fermilab program. A component of such a program is likely to consist of measurements of neutrino properties. Physicists now think that neutrinos could provide answers to some of the puzzling questions not addressed by the Standard Model. In particular, physicists think that neutrinos might be the reason that we exist: their interactions could explain why matter is abundant while antimatter disappeared in our universe. The proposed Long-Baseline Neutrino Experiment aims to find out whether that is the case. It will explore the interactions and transformations of the world's highest-intensity (made possible through SRF R&D) neutrino beam by sending it from Fermilab more than 1,000 kilometers straight through the earth to the largest particle detectors ever built. The detectors could be housed in the proposed DUSEL laboratory. Superconducting radiofrequency is a key enabling technology for state-of-the-art particle accelerators. It is of critical importance to Fermilab 's Project-X, future Linear Colliders, and to future accelerators for high-energy and nuclear physics as well as next-generation light sources such as those based on energy-recovery linacs and free-electron lasers. SRF applications cover a very broad range of accelerator and beam parameters; cost savings in SRF can determine the feasibility of a particular design or whether a project is funded at all. Small improvements in achievable SRF cavity performance can lead to significant reductions in construction and operating costs of major accelerator-based facilities. The basic physics and chemistry governing SRF cavity limits and behavior at the niobium surface is still insufficiently understood, and it is still impossible to guarantee that a particular cavity fabricated and processed according to a particular recipe will actually meet its specifications. No US vendors can match European or Asian vendors in cavity quality, achievable gradient, or production reproducibility. US industry on its own cannot undertake the necessary R&D. Intellectual and practical mentorship of US industry by university and laboratory experts is a step on a path that American industry can follow to help it regain leadership in many specialized high-tech areas, including SRF.The frontiers of science are often shaped by accelerator physics and technology. As examples, SRF has opened up a new world in nuclear physics and neutron production; the short x-ray pulses from free electron lasers will revolutionize atomic and molecular physics, and accelerator science will determine the future of its progenitor, particle physics, where inventions are needed to overcome size and cost limitations.This collaboration is positioned to make substantial progress in understanding, improving, and detailing the important steps in fabricating and processing cavities. The US vendors who become partners in this program will benefit in that they can begin to learn how to successfully compete with the rest of the world on US and international cavity procurements. It is also worth noting that accelerator science is a very forward-looking area for a young scientist to pursue.

超导RF （SRF）开发项目X中微子束到DUSEL的研发被认为是高度相关的，并且可能具有国家和国际重要性。这一研发项目可以实现的科学包括在DUSEL的项目，即南达科他州拟议的深层地下科学与工程实验室。X计划是一系列实验的集合，旨在组成未来的费米实验室项目。这种计划的一个组成部分可能包括对中微子性质的测量。物理学家现在认为，中微子可以为标准模型没有解决的一些令人困惑的问题提供答案。特别是，物理学家认为中微子可能是我们存在的原因：它们的相互作用可以解释为什么物质丰富而反物质在我们的宇宙中消失了。拟议中的长基线中微子实验旨在查明情况是否如此。它将探索世界上最高强度的中微子束（通过SRF R&amp；D实现）的相互作用和转变，将其从费米实验室直接穿过地球1000多公里到达迄今为止建造的最大的粒子探测器。探测器可以安置在拟议的DUSEL实验室中。超导射频是最先进的粒子加速器的关键使能技术。它对费米实验室的x项目、未来的线性对撞机、未来的高能和核物理加速器以及下一代光源（如基于能量回收直线加速器和自由电子激光器的光源）至关重要。SRF应用涵盖了非常广泛的加速器和光束参数；SRF中的成本节约可以决定特定设计的可行性或项目是否得到资助。可实现的SRF腔性能的微小改进可以显著降低主要加速器设施的建设和运营成本。控制SRF空腔极限和铌表面行为的基本物理和化学仍然没有得到充分的了解，并且仍然不可能保证根据特定配方制造和加工的特定空腔实际上符合其规格。在腔体质量、可实现的梯度或生产重现性方面，没有美国供应商可以与欧洲或亚洲供应商相提并论。美国工业本身无法承担必要的研发工作。大学和实验室专家对美国工业的知识和实践指导是美国工业可以遵循的道路上的一步，可以帮助它在许多专门的高科技领域重新获得领导地位，包括SRF。科学的前沿往往是由加速器物理和技术塑造的。例如，SRF开辟了核物理和中子产生的新世界；来自自由电子激光的短x射线脉冲将彻底改变原子和分子物理学，而加速器科学将决定其前身粒子物理学的未来，在粒子物理学中，需要发明来克服尺寸和成本的限制。这次合作将在理解、改进和详细说明制造和加工空腔的重要步骤方面取得实质性进展。成为该项目的合作伙伴的美国供应商将受益，因为他们可以开始学习如何在美国和国际腔采购中成功地与世界其他地区竞争。同样值得注意的是，加速器科学对于年轻科学家来说是一个非常具有前瞻性的领域。
