Certain lanthanide halides have significantly higher light output than NaI:Tl, the comparison standard for scintillators, plus other important properties, including fast decay times and excellent proportionality. Unfortunately, lanthanide halides grown by traditional melt processes have high production costs and limited availability. Crystals are usually limited to about 5 cm x 5 cm, right cylinde ...

COMPUTER MEMORY ARRAYS ARE EXTREMELY VULNERABLE TO ELECTROMAGNETIC DISTURBANCES RESULTING FROM ACCIDENTAL OR HOSTILE ACTIONS. HARDENING AGAINST SUCH EFFECTS CAN BE IMPARTED EITHER BY ADDING EXTERNAL PROTECTION TO EXISTING SYSTEMS OR BY INCORPORATING SURVIVABILITY IN NEW DESIGNS. INHERENT HARDNESS CAN BE IMPARTED TO RANDOM ACCESS MEMORY ARRAYS BY USING THIN FILM FERROELECTRIC MATERIALS AS MEMORY EL ...

CONVENTIONAL INSTRUMENTATION FOR AIRBLAST PRESSURE MEASUREMENTS IN CAVITY SHOTS IS LIMITED IN RISE TIME CAPABILITY. THIS RESULTS IN THE INSTRUMENTATION PROVIDING AN INCORRECT INDICATION OF PEAK PRESSURE, WHICH CREATES DISTORTION IN GENERATED HEIGHT-OF-BURST CURVES. THE DEVELOPMENT OF A FIBER OPTIC AIRBLAST PRESSURE SENSOR BASED ON THE PHOTOELASTIC EFFECT IS PROPOSED. THIS TECHNIQUE PROMISES TO PRO ...

SIMOX MATERIAL IS RAPIDLY BECOMING THE SOI MATERIAL OF CHOICE FOR MANY IC APPLICATIONS, INCLUDING RADIATION HARDENED. A CONSTANT THEME OF CONCERN THROUGHOUT THE DEVELOPMENT OF THIS TECHNOLOGY HAS BEEN THE METALLIC IMPURITY CONTENT IN THE MATERIAL. MAJOR EFFORTS HAVE ADDRESSED THE ELIMINATION OF THE METALLIC CONTAMINATION BY MODIFICATION OF THE IMPLANTATION EQUIPMENT USED TO FABRICATE SIMOX MATERIA ...

IT IS PROPOSED TO DESIGN, BUILD AND TEST A NOVEL SUITE OF XUV AND X-RAY MEASURING INSTRUMENTS FOR RADIATION FROM X-PINCHES. THIS SUITE WILL OFFER SPACE AND TIME RESOLUTION AND COVER EMISSIONS OVER THE ENTIRE COURSE OF THE IMPLOSION, FROM XUV (100-500 EV) TO SFT X-RAYS (1-10KEV). THE SUITE CONSISTS OF AN X-RAY CRYSTAL SPECTROMETER, AN X-RAY PINHOLE CAMERA AND AN XUV PINHOLE CAMERA. THE BASIC DETECT ...
