U.S. forces working in low-level radiation environments have unsatisfactory choices for monitoring radiation exposure. The currently available A/UDR-13 pocket dosimeter is able to meet sensitivity requirements, but is cost prohibitive at ~$400 per unit, and it fails in the high temperature environments faced our military. Careful monitoring and accurate reporting of the exposed dose will reduce t ...

Proliferation of the weapons of mass destruction such as nuclear weapons is a serious threat in the world today. Prevention of the spread of nuclear weapons has reached a state of heightened urgency in recent years, especially since the events on September 11, 2001 and its aftermath. Gamma ray spectrometers are an important tool in checking the proliferation of the nuclear weapons. Important re ...

New technology is needed for the nondestructive inspection (NDI) of microscopic defects in the thin-wall, titanium alloy hydraulic lines used on aircraft. Once mounted on an aircraft, these tubes are difficult to access externally, making inspection of the tube from the inside the most practical method for NDI. The Navy has identified a specific need for the NDI of titanium tubing with diameters r ...

DESCRIPTION (provided by applicant): Real-time or dynamic radiographic imaging (fluoroscopy) provides vital information concerning internal organ structure, flow of contrast agents and in-vivo instrument positioning. Fluoroscopy is a very important modality for cardiac and vascular imaging including subtraction angiography where it is used for locating and evaluating cardiac structures, major v ...

DESCRIPTION (provided by applicant): Radiation Monitoring Devices (RMD) proposes to develop a new dental x-ray imager that will have all the advantages of a digital technology and retain the most desirable aspects of image quality that film emulsions provide. The device will be a blend of two technologies - silicon based imaging arrays and semiconductor x-ray conversion layers. RMD will work on ta ...

DESCRIPTION (provided by applicant): Information on the structure and function of proteins is important for unveiling the biological processes taking place on a molecular level. X-ray crystallography has been successful in determining protein structure, however is not well suited for analyzing hydrogen atoms and water molecules. It has been shown that the thermal neutrons are a far better tool for ...

DESCRIPTION (provided by applicant): Magnetocardiography (MCG) has been shown to offer powerful disease detection and diagnostic capabilities in both humans and animals not readily achieved with standard ECG and echocardiography, including the ability to map ischemic regions in the heart, and monitor arrhythmia. Fetal magnetocardiography (fMCG) has been successfully employed for the non-invasive s ...

78004S Inorganic scintillators are one of the most common detectors used in nuclear and particle physics experiments. Among the important requirements for scintillators are high light output, high sensitivity, low cost, fast response, and good stability. None of the available scintillators satisfy all these requirements. This project will investigate a new class of scintillation materials that ...

The accurate assessment of the electrical and physical characteristics of a PCB (printed circuit board) to determine its condition, operational status and to analyze defects is a difficult challenge. Multi-function, high speed and exceedingly small PCBs point to a need for versatile new automated test equipment (ATE), with generic analysis capabilities that do not rely on the customized hardware a ...

78028S Scintillation spectrometers, consisting of inorganic scintillation crystals coupled to photomultiplier tubes, are an important element of nuclear and elementary particle physics experiments. Performance of the detection systems used in these experiments is often limited by the properties of scitillators available at present. The goal of the proposed project is to investigate a new scintill ...
