Gamma radiation detection has traditionally required single crystal materials that are difficult to produce consistently on an industrial scale. Agiltron has developed a new class of scintillator materials based on composites containing nanoparticles. These so-called nanocomposites exhibit radiation detection characteristics superior to currently available single crystal scintillators. In Phase I ...

IMPULSE RADAR WHICH DERIVES ITS "MAIN BANG", A TRANSIENT, BY EXCITING AN ANTENNA CAVITY WITH A SUBNANOSECOND PULSE HAS BEEN SHOWN TO BE VERY EFFECTIVE FOR INTRUSION DETECTION. A RECENT SBIR PROGRAM COMPLETED FOR DNA RESULTED IN THE DEVELOPMENT OF A NEW LOW COST, LIGHT WEIGHT, RADAR SENSOR FOR THE PROTECTION OF NUCLEAR SITES NOW BEING MARKETED COMMERCIALLY. DURING THE DNA FIELD EXPERIMENTS ON ANIMA ...

THERE IS AN ESTABLISHED NEED FOR A SIMPLE ROBUST TRANSDUCER TO MEASURE PARTICLE VELOCITY IN SEVERE BLAST AND SHOCK ENVIRONMENTS SUCH AS NUCLEAR AND HIGH EXPLOSIVE TESTS. A GAGE CONCEPT IS PROPOSED FOR DEVELOPMENT, BASED ON THE PROVEN MEASUREMENT PRINCIPLES USED IN THE HIGHLY SUCCESSFUL DX GAGE, BUT RECONFIGURED MECHANICALLY AND ELECTRICALLY TO WITHSTAND THE HARSH SHOCK ENVIRONMENTS. THE CONCEPT RE ...

HIGH RANGE (200,000 G) ACCELEROMETERS ARE THE ONLY TRANSDUCERS THAT PROVIDE THE REQUIRED LONG-TERM DATA IN THE ENVIRONMENTS OF INTEREST TO THE BLAST AND SHOCK COMMUNITY. THESE GAGES HAVE A VERY LARGE DYNAMIC RANGE AND NOISE OFTEN MASKS THE LATE TIME (BUT EXTREMELY IMPORTANT) DATA. WE PROPOSE TO DEVELOP A CLOSE COUPLED LOGARITHMIC GAIN SIGNAL CONDITIONING SYSTEM THAT WILL CORRECT THE LATE TIME NOIS ...

We will develop a vapor phase detector of the chemicals/explosives associated with nuclear weaponry. Radioactivity detection allows accurate weapons verification, but provides too much information on the weaponry design. An alternative is to detect otherchemicals associated with nuclear weaponry. EIC Laboratories has successfully developed vapor phase Surface Enhanced Raman Spectroscopy (SERS) ...

CURRENT NUMERICAL COMPUTATIONS TO DESCRIBE NUCLEAR GROUND SHOCK ENVIRONMENTS, NUCLEAR CRATER FORMATION, IMPACT DYNAMICS AND PENETRATION MECHANISMS PRESENTLY EMPLOY EULERIAN-BASED FINITE DIFFERENCE CODES BECAUSE OF THEIR ABILITY TO MODEL THE MASS FLUX PHENOMENA IN TRACKING MATERIAL MOVEMENT THROUGH THE DISCRETIZED SPACE. THE FINITE DIFFERENCE CODES SUFFER IN COMPARISON TO FINITE ELEMENT CODES, HOWE ...

KTECH PROPOSES TO DEVELOP OPTICAL HOPKINSON BAR PRESSURE GAUGES FOR MEASUREMENT OF AIRBLAST ON UNDERGROUND NUCLEAR EVENTS. THE BARS WILL BE MADE OF SINGLE CRYSTAL SAPPHIRE WHICH HAS A MEASURED YIELD STRENGTH IN EXCESS OF 10 GPA. THESE GAUGES WILL HAVE A RISE TIME OF ABOUT 2 US OF DATA. DURING PHASE I, WE WILL CONSTRUCT AND CALIBRATE A STRESS-INDUCED BIREFRINGENCE GAUGE (SIBG) WHICH WOULD NEED NO E ...

The overall objective of the HSGR Program is to develop a high sensitivity military GPS receiver to provide reliable GPS navigation, under weak GPS signal conditions, to ground based military GPS users. Mayflower’s approach to meet this HSGR program objective is to design, develop and incorporate “high-sensitivity” signal processing enhancements (namely, Vector Tracking (VT) and Multi-bit GP ...

UNDER THIS EFFORT, WE WILL DEVELOP A PORTABLE MEMORY TESTER UNIQUELY DESIGNED TO PERFORM THE TYPES OF TESTS REQUIRED FOR RADIATION EFFECTS CHARACTERIZATION. SPECIFICALLY, IT WILL PERFORM TESTS TO CHARATERIZE SINGLE EVENT PHENOMENA (SEP), TOTAL DOSE IONIZING EFFECTS, DOSE RATE, AND RAPID ANNEALING PHENOMENA. IT WILL COMBINE KEY FEATURES OF GENERAL PURPOSE ASIC TESTERS AND DEDICATED MEMORY TESTERS R ...

The project goal is to develop an alternative infrasound monitoring system with piezoelectric sensors for use under the Comprehensive Test Ban Treaty. These sensors will have several advantages over the microbarograph system that forms the baseline forthe IMS. As an all-electronic system, the novel sensor would be far simpler than the baseline, with no moving parts or piping. It will be more ro ...
