Survival of present day microelectronic circuits depends on their protection from self generated and external electromagnetic interference. This proposal is oriented toward the class of interference generally referred to as overvoltage transients. Means for mitigating these transients include gas discharge tubes, and various solid state devices. Each of these has their own advantages in particu ...

THE RADIOBIOLOGICAL EFFECTS FROM INITIAL AND LINGERING AIRBORNE AND SURFACE FALLOUT NUCLEAR RADIATION ARE KEY CONSIDERATIONS FOR CONUS POSTATTACT STRATEGIC RECOVERY OPERATIONS PLANNING. IN THIS PROPOSED EFFORT WE INTEND TO APPLY THE KNOWLEDGE GAINED FROM THE DNA INTERME DIATE DOSE PROGRAM (IDP) AND PROVIDE A TIMELY UPDATE OF THE SCOPE OF RADIOBIOLOGICAL EFFECTS ON INDIVIDUALS ASSUMING VARIOUS ROLE ...

Using distributed interactive simulation (DIS) to conduct effective training, analyses, or mission support in a tactical nuclear weapons effects (NWE) environment requires realistic computer generated forces (CGF) that are sensitive to such effects. This level of sensitivity requires CGF to apply valid and reliable speed-accuracy measures of environmental effects on human performance within the D ...

We propose to design a compact, multiple purpose electromagnetic sensor for monitoring the extremely low frequency (ELF), very low frequency (VLF), and low frequency (LF) spectrum. Our goal is to design a modular, low cost sensor capable of being configured for multiple applications and capable of being employed in remote, unattended sensor networks. We describe three applications or scenarios t ...

SUBSTANTIAL PROGRESS HAS BEEN MADE IN RECENT YEARS TO DEVELOP AND VALIDATE MODELS WHICH CAN PREDICT THE PHYSICAL EFFECTS OF NUCLEAR WEAPONS ON STRATEGIC STRUCTURES. SIGNIFICANT UNCERTAINTIES REMAIN, HOWEVER, IN THE CONFIDENCE LEVELS ATTRIBUTABLE TO THESE PREDICTIVE CAPABILITIES. THIS APPROACH WOULD IDENTIFY AND PRIORITIZE THOSE ACTIVITIES, ALONG WITH THEIR ASSOCIATED BUDGETARY AND SCHEDULING CONSI ...

THIS PROPOSAL IS PREPARED IN DIRECT RESPONSE TO THE NRC'S SOLICITATION FOR AN IMPROVED DEVICE TO MEASURE AIR MOVEMENT FOR PERSONNEL RADIATION PROTECTION AND HEALTH PHYSICS APPLICATIONS IN NUCLEAR FACILITIES. THE PURPOSE OF THE NEW DEVICE IS TO PROPERLY LOCATE AIR SAMPLERS SO THAT THE AIR SAMPLED IS REPRESENTATIVE OF THE AIR INHALED BY WORKERS. ALTHOUGH AIR FLOW RATE SENSORS SUCH AS ANEMOMETERS ARE ...

THE DISTRIBUTION OF THE MAGNETIC FIELD IN A HIGH CURRENT PLASMA DEVICE PROVIDES IMPORTANT INFORMATION ABOUT THE DEVICES OPERATION. TRADITIONAL FARADAY ROTATION, ZEEMAN EMISSION SPECTROSCOPY, AND MAGNETIC PROBE TECHNIQUES SUFFER FROM POOR SPATIAL RESOLUTION BECAUSE THE MAGNETIC FIELD EFFECT IS INTEGRATED ALONG THE LINE OF SIGHT FOR THE OPTICAL TECHNIQUE AND THE PROBES PERTURB THE PLASMAS. A LASER I ...
