ARI-MA Superheated emulsions for nuclear material detection

[388997] d' errico该奖项将支持用于快中子的大体积过热乳剂探测器的开发。该仪器将具有100%的占空比，对伽马不敏感，并且对瓦谱的较高部分（即能量超过3兆电子伏特的中子）敏感。在20atm下，通过光学读出退火，可以在5秒内快速计数气泡室探测器中的气泡。声学和光学读出方法将被评估。这是在氦-3资源枯竭的情况下解决中子探测需求的一个新概念。这项建议的更广泛影响是通过让下一代核科学家和工程师参与尖端研究活动来培训他们。PI计划加强和发展课程，其中将包括与放射源的动手实验室实验。合作的多学科性质将使学生接触到广泛的经验，这将由参与的教师提供的共同指导促进。

1038897d'ErricoThis award will support the development of a large volume superheated emulsion detector for fast neutrons. The proposed instrument will have a 100% duty cycle, be insensitive to gammas, and be sensitive to the higher parts of the Watt spectrum i.e. neutrons with energies over 3 MeV. The bubbles in this bubble chamber-like detector will be counted by optical readout annealing fairly quickly in 5 seconds at 20 atm. Both acoustic and optical readout methods will be evaluated. It is a novel concept to address the need for neutron detection within the context of depleted resources of He-3.The broader impacts of this proposal address the training of the next generation of nuclear scientists and engineers by engaging them in cutting-edge research activities. The PI plans to enhance and develop courses, which will include hands-on laboratory experiments with radiation sources. The multi-disciplinary nature of the collaboration will expose students to a broad range of experiences, which will be facilitated by co-mentoring provided by the faculty involved.
