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.

1038897 d 'Errico该奖项将支持开发用于快速中子的大容量过热乳胶探测器。 拟议的仪器将有一个100%的占空比，对伽马射线不敏感，并对瓦特光谱的较高部分，即能量超过3兆电子伏的中子敏感。 这种气泡室状检测器中的气泡将在20 atm下通过光学读出退火在5秒内相当快地计数。 声学和光学读出方法将进行评估。 这是一个新的概念，以满足中子探测的背景下，耗尽的He-3资源的需求。更广泛的影响，这一建议涉及下一代的核科学家和工程师的培训，让他们参与尖端的研究活动。PI计划加强和开发课程，其中将包括使用辐射源的实验室实验。合作的多学科性质将使学生接触到广泛的经验，这将通过参与教师提供的共同指导来促进。
