RII Track-4: Technology Development for the Next-Generation of Ground-Based Cosmic Microwave Background Instrumentation at Argonne National Lab

测量宇宙微波背景(CMB)是研究和理解我们宇宙的有力工具。CMB-S4是将进行下一代宇宙微波背景测量的项目，被命名为‘S4’，因为它建立在该领域前三代技术开发的基础上。这项EPSCoR RII Track 4奖学金将为PI提供一个独特的、及时的机会，让他们在阿贡国家实验室(ANL)为CMB-S4开发技术。这项奖学金还将通过支持国际和平协会仪器研究的扩展，提高国际和平协会总部机构--新墨西哥大学(UNM)的研究能力，因为该研究有许多学生参与的机会。UNM是一所大型公立研究型大学，被归类为R1大学，是研究活动的最高水平，也是一个少数族裔机构和西班牙裔服务机构。这项EPSCoR RII Track 4奖学金将支持Argonne国家实验室为下一代宇宙微波背景项目CMB-S4进行读出开发的工作。这位名叫达西·巴伦的少年是位于阿尔伯克基的新墨西哥大学物理系的早期教员，也是新成立的CMB-S4合作项目的成员。研究员主持人是艾米·本德，她是阿贡国家实验室实验宇宙学小组的成员，也是CMB-S4读出开发小组的负责人。每一代新的实验都通过探测器制造、读出技术和低温技术的进步在灵敏度方面取得了飞跃。该研究金的工作包括促进制定CMB-S4仪器要求和复杂的低温测试基础设施，这是这一敏感新时代取得成功所必需的。PI在阿贡的实验宇宙学小组的官邸将把他们嵌入一个多学科小组，其中包括一个17,000平方英尺的纳米制造设施，为CMB-S4生产原型，以及多个亚开尔文低温试验台，用于设备表征、原型测试和其他技术开发工作。PI将为CMB-S4开发测试硬件和程序，并将在PI的本土机构复制这种测试能力。该奖项反映了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。

Measurements of cosmic microwave background (CMB) are a powerful tool to study and understand our universe. CMB-S4 is the project that will make the next generation of cosmic microwave background measurements, named ‘S4’ because it is building on three prior generations of technology development in this field. This EPSCoR RII Track 4 fellowship will provide the PI with a unique, timely opportunity to develop technology for CMB-S4 at Argonne National Laboratory (ANL). This fellowship will also enable enhancement in research capacity at the PI’s home institution, the University of New Mexico (UNM), by supporting the expansion of the PI’s instrumentation research, which has many opportunities for student involvement. UNM is a large public research university that is categorized as an R1 university, the highest level of research activity, and is also a minority institution and a Hispanic-serving institution.This EPSCoR RII Track 4 fellowship will support work at Argonne National Lab on readout development for the next-generation cosmic microwave background project CMB-S4. The PI, Darcy Barron, is early-career faculty in the physics department at the University of New Mexico in Albuquerque and a member of the newly formed CMB-S4 collaboration. The fellowship host is Amy Bender, a member of the Experimental Cosmology group at Argonne National Lab, and a leader of the readout development group for CMB-S4. Each new generation of experiments has made a leap in sensitivity through advances in detector fabrication, readout technology, and cryogenics. The work for this fellowship includes contributing to the development of the CMB-S4 instrument requirements and the complex cryogenic testing infrastructure necessary for the success of this new era of sensitivity. The PI’s residence with the Experimental Cosmology group at Argonne will embed them in a multi-disciplinary group with facilities including a 17,000-square-foot nanofabrication facility producing prototypes for CMB-S4, and multiple sub-Kelvin cryogenic test stands for device characterization, prototype testing, and other technology development work. The PI will develop testing hardware and procedures for CMB-S4 and will duplicate this capacity for testing at the PI’s home institution.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.
