Alameda Applied Sciences Corporation (AASC) proposes to develop an all-solid-state, compact, portable, multi-gigawatt poer modulator for electron and ion beam diodes, high power microwave and x-ray sources. This modulator is based on Inductive Energy Store (IES) using an array of Diamond Opening Switches for power compression. Because power amplification using IES requires a much smaller volume ...

Alameda Applied Sciences Corporation (AASC) proposes to develop a new type of interferometer that is compact and portable and can be used to make in-situ measurements of gases and plasmas. This interferometer uses polarization maintaining optical fibers and diode lasers to duplicate the capabilities of existing Mach-Zender interferometers that use dicrete optical elements such as mirrors, lenses ...

Alameda Applied Sciences Corporation (AASC) proposes to develop a new class of real time integrating diamond radiation dosimeters. In Phase I AASC will demonstrate the feasibility of using diamond radiation detectors for monitoring personnel radiation dose. The sensitivity of these detectors will be determined and a concept design for a pocket real time dosimeter will be completed. The Phase ...

CURRENT ACTIVITY WITHIN THE NRC AND THE NUCLEAR INDUSTRY SEEKS TO EXPLOIT THE BENEFITS OF PRA IN RISK-BASED APPROACHES TO RELIEVE REGULATORY BURDEN ON THE ECONOMICALLY THREATENED NUCLEAR POWER PLANTS. THE ACCIDENT PREVENTION GROUP HAS BEEN DEVELOPING THE CONCEPT OF AN INTEGRATED RISK MANAGEMENT PROGRAM (IRMP) TOWARD SUCH GOALS. A KEY ELEMENT OF AN IRMP IS AN "OPERATIONAL RISK MODEL" OF THE NPP THA ...

AN EXPERIMENT IS PROPOSED TO DEMONSTRATE THAT TRANSIENT X-RAY RADIATION FROM THE PHYSICS INTERNATIONAL PULSERAD 1150 FLASH X-RAY MACHINE WILL CAUSE A REPRESENTATIVE HIGH TEMPERATURE SUPERCONDUCTING (HTS) DEVICE TO MALFUNCTION BY REVERTING TO NORMAL CONDUCTIVITY. INTEREST IN THIS PHENOMENON IS MOTIVATED BY THE ANTICIPATED INCORPORATION OF HTS THIN FILM TECHNOLOGY IN DEFENSE ELECTRONICS, ESPECIALLY ...

The nuclear weapons community has traditionally focused on the next generation or level of weapon capability complimented by gathering and analysis of actual test data. Now, with the cessation of actual weapons testing, there is an increased need to use the actual test data in modeling techniques to better understand the phenomenology and potential effects of nuclear weapons. The first phase of ...

Turbulence of gas flows by its very nature is one of the most difficult things to model and measure. We propose to develop a new way of measuring the turbulence and to compare these measurements to predictions using the k-epsilon model. Typical measurements, in the past, use smoke, Schlierin or shadow graph techniques to visually infer turbulence characteristics. These features are either motio ...

The DM1 module that is a building block of DSWA's DECADE simulator has excellent electrical performance, but the final radiation pulse is erratic and often unsatisfactory. The probable cause is a parasitic current in ions, or through a diode plasma. This proposal is to evaluate a diode configuration that should suppress ions and plasma, namely a cathode of carbon fibers covered with cesium iodid ...

We propose to develop a differential absorption spectrometer that is small enough to be compatible with a test package in a bremsstrahlung test of electronics. In contrast to previous spectrometers, which use individual filter-detector combinations, the present instrument consists of concentric hemispherical shells. This design minimizes the spectrometer's mass, allowing it to be placed in front ...
