Accelerators used for nuclear-physics research require megawatts of radio-frequency energy. They currently employ vacuum-tube power amplifiers or conventional solid-state amplifiers that are inefficient and therefore consume a great deal of prime power. Many other applications including semiconductor processing, cellular-telephone base station transmitters and military communication systems simila ...

ABSTRACT: The objective of this proposal is to develop 202 inspection techniques that standardize both the inspection process and any defect data captured as part of the inspection in support of engineering analysis on 202 processes. The Oklahoma City Air Logistics Center (OC-ALC) current processes are manual, paper based solutions that vary greatly based on the background and expertise of the p ...

This STTR project seeks to develop high-voltage, high-performance Solid-State Fault Current Controller (SSFCC) technology utilizing Silicon Carbide (SiC) super gate-turn-off thyristors (SGTOs). Due to improved technical advantages, the proposed SSFCC technology will minimize fault-related power quality issues (i.e., voltage sags, oscillations, harmonics, etc.), improve network reliability (i.e., m ...

The terminal objective of this Phase II work will be the development of a harsh environment non-intrusive self-powered wireless sensor-transmitter capable of operation to 225 °C and survivable to 300 °C. The developed wireless sensor transmitter will acquire bearing parametric data, such as temperature and vibration information, and wirelessly transmit that data to an engine PHM system. The el ...

In order to realize the benefits of formation flying multi-spacecraft clusters, four key elements must be present: 1. Broadband inter-spacecraft communications to enable the transport of high resolution sensor data. 2. Precision inter-spacecraft timing synchronization to enable precise multi-sensor sampling throughout the cluster. 3. Precision inter-spacecraft relative range to enable the determin ...

Standoff detectors are required to detect IEDs. These detectectors are needed to save the lives of American soldiers. QuantaSpec has developed patent pending methods for long-range, sensitive, and selective standoff detection of explosives. These methods have already demonstrated sensitive remote detection of explosive vapors under previous efforts. QuantaSpec's multidisciplinary team will dem ...
