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.

宇宙微波背景（CMB）的测量是研究和了解我们宇宙的强大工具。 CMB-S4是将使下一代宇宙微波背景测量的项目称为“ S4”，因为它是在该领域的三代技术开发的基础上建立的。 EPSCOR RII轨道4奖学金将为PI提供独特的，及时的机会，为Argonne National Laboratory（ANL）开发CMB-S4的技术。这项奖学金还将通过支持PI仪器研究的扩展来扩大新墨西哥大学（UNM）的PI家庭机构（UNM）的研究能力，这有许多学生参与。 UNM是一所大型公共研究大学，被归类为R1大学，最高水平的研究活动，也是少数族裔机构和西班牙裔服务机构。这项EPSCOR RII TRECK 4奖学金将支持Argonne National Lab在Argonne National实验室的下一代COSMIC Microhave Microlofave Project Project Project Project Project Project Project Project Project Project Project cmb-s4。 PI Darcy Barron是阿尔伯克基新墨西哥大学物理系的早期职业学院，也是新成立的CMB-S4合作成员。奖学金主持人是Amy Bender，他是Argonne National Lab实验宇宙学小组的成员，也是CMB-S4读数开发小组的领导者。每个新一代的实验都通过检测器制造，读出技术和低温学的进步来取得敏感性。这项奖学金的工作包括为CMB-S4仪器要求的发展做出贡献，以及对于这个新的敏感性时代成功所必需的复杂的低温测试基础设施。在Argonne的实验宇宙学组的PI住所将将它们嵌入一个多学科的组中，其中包括17,000平方英尺的纳米型纳米化设施，为CMB-S4生产原型，以及多个子-Kelvin的低温测试，用于设备表征，原型测试和其他技术开发。 PI将开发针对CMB-S4的测试硬件和程序，并将在PI的家庭机构中复制这种测试能力。该奖项反映了NSF的法定任务，并且是否使用基金会的智力优点和更广泛的影响标准，通过评估我们被评估诚实。
