Liquid helium is critical for a great many of the research needs at the University of Colorado Boulder, particularly with the extensive recent and coming growth in the areas of quantum sciences and engineering. The Physics Department has operated a helium liquefier for almost two decades, while also providing liquid to other users across campus. Unfortunately, the present liquefier is of a style and age that is extremely complicated to run and maintain and it is no longer supported by the manufacturer. The present project includes replacing the existing liquefier with a much more modern and simple system, that due to its design will have much higher reliability. The infrastructure for supporting such a facility is already in-place and will be reutilized. Other infrastructure across our campus is also in-place, as the Nuclear Magnetic Resonance (NMR) facilities in both Chemistry and the Biofrontiers Institute, which operate 7 distinct superconducting-magnet NMR instruments, have helium capture and compression facilities, but will have no way to reliquefy the helium. A similar capture and compression facility will be installed in Engineering as part of this project, enabling it to serve all present liquid helium needs in the campus - including 40 different research groups representing 8 Departments, 3 Colleges, and 5 Research institutes. The impact on the teaching program will also be strong – the superconducting-magnet NMR systems are directly utilized in 5 distinct undergraduate courses with an enrollment of ~ 1300 students/year.

The Physics Department has operated a helium liquefier for almost two decades, while also providing liquid to other users across campus. Unfortunately, the present liquefier is of a style and age that is extremely complicated to run and maintain and it is no longer supported by the manufacturer. The present proposal includes replacing the existing liquefier with a much more modern and simple system based upon pulse-tube technology, that due to its design will have much higher reliability. The infrastructure for supporting such a facility, including piping and gas monitoring from across the Physics/JILA complex is already in-place and will be reutilized. Other infrastructure across the campus is also in-place, as the Nuclear Magnetic Resonance (NMR) facilities in both Chemistry and the Biofrontiers Institute, which operate 7 distinct superconducting-magnet NMR instruments, have helium capture and compression facilities, but will have no way to reliquefy the helium. A similar capture and compression facility will be installed in Engineering as part of this project, enabling it to serve all present liquid helium needs in the campus. Many of the experimental systems can’t be replaced by “dry” or recirculating helium systems, due for example to the need for ultra-low vibrations. In addition to the work on quantum systems in Physics, JILA, and Engineering, the NMR systems serve 40 different research groups representing 8 Departments, 3 Colleges, and 5 Research institutes. The impact on teaching program will also be strong – the superconducting-magnet NMR systems are directly utilized in 5 distinct undergraduate courses with an enrollment of ~ 1300 students/year.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.

液体对量子科学和工程领域的CORADO TORLIEN的氦气至关重要。是一种风格和年龄，使其维护不断支持此类王牌并将重新融合我们的其他基础设施，这也将在Ourosso遍布地位，因为化学和Tittute中的核磁共振（NMR）设施（NMR）设施，该设施运行7种不同的超导型MAGNET NMR仪器必须将氦气的一部分重新提供，以满足校园中的所有氦气需求，包括40个不同的研究小组，代表8个部门，3个学院和5个研究机构。强 - 超导型NMR系统直接在5个不同的本科课程中使用，闭上了约1300名学生/年的学生。量子科学和工程部门在校园内经营着近二十年的用户，目前的Liquefier是一种风格和年龄。 - 由于设计而导致的管道将更加可靠。由于化学和生物占用器中的nucklear磁共振（NMR）设施（运行7个不同的超导型马格内特NMR仪器）具有氦气捕获和压缩设施氦气。在该项目中，除了在物理，吉拉和工程学的量子系统上，还可以满足校园的所有液体氦气需求。酸痛的计划也将很强大 - 超导磁铁NMR系统直接在5个不同的地下课程中使用，招收〜1300名学生/youar.this nsf'sflects，并获得了值得使用OUDDAINTAINT的智力优先级和智力的功能和智力，更广泛的影响审查标准。
