NOVA Scientific, Inc., teamed with the Electronics Group of Oak Ridge National Laboratory, proposes to construct very large area Microchannel Plate neutron detectors. The applications of these much larger format detectors will serve an exceptionally broad range of government agencies from neutron scattering detectors for DOE to nuclear material panel detectors for NNSA, and ultimately to nuclear m ...

Frac fluids are viscous solutions that are pumped under high pressure to fracture subsurface formations for recovery of natural gas. As it is pumped to the surface, the flowback water picks up large quantities of various contaminants that make it difficult to dispose or recycle. Though this water contains hazardous substances such as heavy metals (i.e. copper, lead, zinc, and cadmium), arsenic, se ...

Future magnets for Fusion Energy Systems require superconducting cables with improved high critical current carrying capacity at high magnetic fields, 20 Kelvin operation, low AC losses and lower cost. A new method of fabricating a high current cable with 2G HTS tapes has been developed that will improve the engineering current density achievable. Commercial Applications and Other Benefits: Fut ...

To reduce the cost of new hardware development, the Missile Defense Agency (MDA) is developing fast new computational tools that enable in-the-loop hardware testing. The MDA and contractors have developed high-fidelity scene modeling tools such as the Fast Line-of-sight Imagery for Target and Exhaust-plume Signatures (FLITES) to test optical signature trackers. Currently, these high-speed tools ar ...

An innovative, super-miniature, fast-switching array-based photonic time delay device is being developed for the active electronically scanned-array (AESA) MDA and Navy radars. The design is based on the fast electro-optic effect, the super miniature fiber-lens collimation array, and the existing WDM photonic true time delay technologies. In Phase I Agiltron has successfully demonstrated the core ...

Heat exchangers are a used in a commercial, residential, and military cooling systems. Their thermal performance is measured by their ability to efficiently transfer heat. By increasing the heat exchanger efficiency, the size and weight of the system can be reduced. This work explores the use of twisted tape technologies and the use of advanced nanofluids for improving thermal performance. ACT ...

There is a growing demand for power electronics that can operate under the high temperature and high power conditions that will be encountered in Hybrid Electric Vehicles (HEV). As the coolant temperature used to dissipate heat from electronics increases, the operation of power semiconductor devices such as Insulated Gate Bipolar Transistors (IGBTs) becomes severely limited in order that the safe ...

Carbon dioxide is monitored with high precision at hundreds of monitoring stations, world-wide. Those measurements rely upon frequent calibration using high pressure gas cylinders, which must be certified and then shipped to remote locations. Current calibration procedures are both labor intensive and expensive. Continuous monitoring of CO2 at remote locations presents particularly difficult cali ...

New solid-state photomultipliers (SSPMs) need compact integrated circuitry for readout if such photodetectors are going to be implemented in high-energy physics, nuclear physics, or nuclear medical imaging applications. The aim of this work is to significantly improve the bandwidth in reading out arrays of SSPMs by developing a custom ASIC (Application Specific Integrated Circuit). This ASIC will ...

High power microwave (HPM) sources have been developed over the past few decades for many important DoD missions ranging from electronic warfare to intentional EMI to impulse radar. In this proposal, we describe an integrated program that seeks to develop innovative solutions based on mesoband source and antenna technology to improve the effectiveness of HPM-based BMD systems. Our research will ...
