A neutron detector includes a microchannel plate having a structure that defines a plurality of microchannels, and layers of materials disposed on walls of the microchannels. The layers include a layer of neutron sensitive material, a layer of semiconducting material, and a layer of electron emissive material. For example, the layer of neutron sensitive material can include boron-10, lithium-6, or gadolinium.

A device includes a neutron-sensitive composition. The composition includes, in weight percent, a non-zero amount of aluminum oxide (e.g., approximately 1% to approximately 3.5% aluminum oxide), greater than 12% (e.g., approximately 12% to approximately 17%) boron oxide, greater than approximately 60% silicon oxide (e.g., approximately 62% to approximately 68% silicon oxide), and a non-zero amount of sodium oxide (e.g., approximately 10% to approximately 14% sodium oxide). The device is capable of interacting with neutrons to form an electron cascade.

A method for detecting a neutron includes providing a first voltage to an input electrode of a microchannel plate, providing a second voltage to an output electrode of the microchannel plate, the second voltage being more positive than the first voltage, measuring a signal on the output electrode, and detecting a neutron based on a comparison of the signal at the output electrode with a baseline value.

The project is developing a new sensor technology that can measure carbon dioxide levels with precision that matches or exceeds the state-of-the-art performance, but will reduce the price dramatically, and will for the first time enable instruments deployed in remote locations to operate unattended for long periods of time. A laboratory prototype was designed, constructed, and demonstrated. It exceeded the performance objectives for Phase 1 by a wide margin and clearly proved the feasibility of the proposed approach. In the first year, engineering prototypes will be constructed to address remaining design questions and verify robustness for unattended operation; the capability to measure water vapor concentration in air will also be added so the instrument can report the dry mole fraction of carbon dioxide in air (the amount of carbon dioxide per amount of dry air). In the second year, manufacturing prototypes will be constructed to validate manufacturing approaches suitable for high-volume, low-cost production and to enable testing under extreme environmental conditions. Commercial Applications and OtherBenefits: Government and university scientists will deploy the proposed analyzers in distributed networks to measure carbon dioxide in the atmosphere at local, regional, and global scales. These instruments will benefit the public by collecting the information needed to formulate policies that efficiently mitigate the impacts of climate change while minimizing the cost to society.
