The Gérard Mourou Center for Ultrafast Optical Science at the University of Michigan will operate a new laser user facility to be called NSF Zettawatt-Equivalent Ultrashort pulse laser System (ZEUS) facility. The NSF ZEUS facility will operate the most powerful laser in the US and will provide unique and world-leading capabilities for scientific research. The NSF ZEUS facility will have an open and transparent review process for facility access with at least 30 weeks per year dedicated to external user experiments. The facility will have local and national economic and societal impact through training of students and post-doctoral researchers at universities throughout the US, with specific outreach efforts focused on increasing demographic diversity of the ZEUS user community. The facility will also foster innovation in the field of laser technology, potentially enabling formation of new high tech companies.The new NSF ZEUS user facility will include a multi-beam 3 PetaWatt (PW) laser system that will have three radiation-shielded experimental target areas to accommodate differing experimental configurations for users. The ZEUS laser system will have three modes of operation, either for experiments using a single 3 PW beamline, dual beam 2.5 PW/500 TeraWatt (TW) or up to 300 TW at higher repetition rate. A nanosecond-duration 75 J shock driver beamline for generating high-energy-density states of matter will also be available. The repetition rate of ZEUS at full power will be one shot per minute but will also have a higher repetition rate mode at 5 Hz for powers up to 300 TW. This additional operational mode will enable a significant amount of data to be taken, which is particularly important for x-ray (up to 50 keV) and neutron (up to 20 MeV) imaging applications. These bursts of x-rays and neutrons produced by ZEUS will have ultra-short pulse duration and can also be used for probing dynamic events at picosecond or femtosecond temporal resolution.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.

密歇根大学的GérardMourou Ultrafast光学科学中心将经营一个新的激光用户设施，称为NSF Zettawatt等效脉冲激光系统（ZEUS）设施。 NSF宙斯设施将运营美国最强大的激光，并为科学研究提供独特而世界领先的功能。 NSF ZEUS设施将采用开放透明的审核过程，以访问设施，每年至少30周专用于外部用户实验。该设施将通过对全美大学的学生和博士后研究人员进行培训以及专门的外展工作，以增加宙斯用户社区的人口多样性，从而产生地方和国家经济和社会的影响。该设施还将在激光技术领域促进创新，从而有可能形成新的高科技公司。新的NSF宙斯用户设施将包括一个多光束3 Petawatt（PW）激光系统，该系统将具有三个辐射屏蔽的实验目标区域，以适应用户的不同实验配置。宙斯激光系统将具有三种操作模式，用于使用单个3 PW梁线，双光束2.5 PW/500 terawatt（TW）或以较高的重复速率最多300 TW。纳秒持续时间75 J减震驱动器光束线，用于产生高能密度的物质状态。宙斯在全功率上的重复率为每分钟一击，但在5 Hz的功率下，最高300 TW的重复率模式也将具有更高的重复率模式。这种额外的操作模式将使大量数据获取，这对于X射线（最多50 KEV）和中子（最多20 MeV）成像应用程序尤其重要。宙斯产生的X射线和中子的爆发将具有超短脉冲的持续时间，也可用于在Picsecond或Qpostsecond临时分辨率上探测动态事件。该奖项反映了NSF的法定任务，并被认为是通过使用该基金会的知识分子和更广泛影响的评估来评估Criteria的智力。
