Neutrinos, the “ghost” particles of fundamental physics, are the only know particle that clearly shows deviations from the predictions the standard model of particle physics. The Ricochet experiment will probe neutrinos using a new interaction which was only discovered in 2017 and provides a new way to study neutrino properties and possibly understand why neutrinos deviate from standard model predictions. Neutrinos might hold the key to understanding new physics beyond our current models; finding and understanding these new physics is a top question in nuclear and particle physics today and would lay the groundwork for a completely new revolution in nuclear, particle, and quantum physics. Ricochet will place an array of 36 detectors operating at a temperature just above absolute zero and eight meters from the core of a nuclear reactor in Grenoble, France. Nuclear reactors are the world’s strongest neutrino sources and placing these low-energy-threshold detectors so close to the reactor core will allow detection of tens of neutrino events per day, enabling the most accurate neutrino spectrum measurement to date. This project serves as a training ground for future scientists, as most of this work is done by graduate students and postdocs who not only design and fabricate the detectors but put together and operate the experiment and analyze and publish the results. This work has the following objectives: (1) design, build, install, commission, and operate nine of the detectors for Ricochet Phase 1 at the ILL nuclear reactor, (2) perform the analysis of the Ricochet data from all 36 crystals to produce the highest precision Coherent Elastic Neutrino-Nucleus Scattering (CEvNS) spectrum measurement to date and search for new physics, (3) continue Northwestern’s synergistic R&D program to use our Transition-Edge Sensor (TES) detectors for future CEvNS and neutrinoless double-beta decay (0nbb) experiments, and (4) train a new generation of neutrino experimental physicists. The Q-array is a 9-detector instrument that will demonstrate superconducting targets for reactor CEvNS measurements, provide target complementarity to the Ge-based CryoCube (the two of which form the payload of Ricochet phase 1), and lay the groundwork for implementing SQUID multiplexing for future neutrino cryogenic experiments with thousands of TES channels. Northwestern will participate in the full analysis of the Ricochet experiment, combining the 27 Ge detectors from the CryoCube and the nine Zn detectors from the Q-array to obtain world-leading sensitivity to the CEvNS process, making a percent-level measurement of the spectrum, and searching for new physics through Non-Standard Interaction modifications to the spectrum. Northwestern will optimize the TES modular architecture for future CEvNS and 0nbb experiments that will require excellent resolution, fast response, and thousands of channels. This will include demonstration of the TES technology on Lithium-Molybdate crystals in a prototype TES-based detector for CUPID 1-TON, and also demonstrate a TES-based Ge Ricochet Phase 2 detector with ionization readout. These activities will provide fertile ground for training of postdoctoral researchers, graduate students, and undergraduates, while sharing the excitement of science with the broader public. Finally, this work has a broad impact that extends beyond neutrino physics. Besides neutrino physics, the detectors being developed will also have applications in nuclear reactor monitoring applications, dark matter, and other low-threshold, high-energy resolution applications.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

中微子是基础物理学中的“幽灵”粒子，它是目前已知的唯一一种明显偏离粒子物理标准模型预测的粒子。跳跃实验将使用2017年才发现的一种新的相互作用来探测中微子，并为研究中微子的性质和可能理解中微子偏离标准模型预测的原因提供了一种新的方法。除了我们目前的模型，中微子可能是理解新物理学的关键；发现和理解这些新物理学是当今核物理和粒子物理学的首要问题，并将为核、粒子和量子物理学中的一场全新革命奠定基础。Reochet将在距离法国格勒诺布尔核反应堆核心8米的绝对零度以上的温度下放置由36个探测器组成的阵列。核反应堆是世界上最强大的中微子源，将这些低能量门槛探测器放在离反应堆核心如此近的地方，每天可以探测到数十次中微子事件，从而实现迄今为止最准确的中微子光谱测量。该项目是未来科学家的培训基地，因为大部分工作是由研究生和博士后完成的，他们不仅设计和制造探测器，而且组装和操作实验，分析和发布结果。这项工作有以下目标：(1)设计、建造、安装、调试和运行病态核反应堆跳跃第一阶段的9个探测器，(2)对所有36个晶体的跳跃数据进行分析，以产生迄今最高精度的相干弹性中微子-核散射(CEvNS)谱测量并寻找新的物理，(3)继续西北大学的协同研发计划，将我们的过渡缘传感器(TES)探测器用于未来的CEvNS和无中微子双β衰变(0NBB)实验，以及(4)培训新一代中微子实验物理学家。Q-ARRAY是一种9探测器仪器，将演示用于反应堆CEvNS测量的超导目标，为基于Ge的CryoCube提供目标互补(两者构成跳跃第一阶段的有效载荷)，并为未来具有数千个TES通道的中微子低温实验实现SQUID多路传输奠定基础。西北大学将参与对跳跃实验的全面分析，结合来自CryoCube的27个Ge探测器和来自Q阵列的9个锌探测器，获得对CEvNS过程的世界领先的灵敏度，对光谱进行百分比级测量，并通过对光谱的非标准相互作用修改来寻找新的物理。西北大学将为未来的CEVN和0NBB实验优化TES模块架构，这些实验将需要出色的分辨率、快速的响应和数千个通道。这将包括在丘比特1吨探测器原型中演示钼酸锂晶体上的TES技术，还将演示具有电离读出功能的基于TES的GE跳跃第二相探测器。这些活动将为培养博士后研究人员、研究生和本科生提供肥沃的土壤，同时与更广泛的公众分享科学的兴奋。最后，这项工作具有超越中微子物理学的广泛影响。除了中微子物理，正在开发的探测器还将应用于核反应堆监测应用、暗物质和其他低门槛、高能分辨率应用。这一奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。
