ELECTRONICS UPGRADE OF HIGH RESOLUTION MASS SPECTROMETERS

Description: High resolution mass spectrometers are specialized systems that allow researchers to determine the exact mass of samples to four significant digits by using magnetic and electronic sector mass analyzers. Many of the systems in use today at research laboratories and universities were designed and built more than two decades ago. The manufacturers of these systems have abandoned the support for some of the mass spectrometers and parts to power and control them have become scarce or obsolete. The … more

Process, product, and waste-stream monitoring with fiber optics

Description: Fiber optic technology, motivated by communications and defense applications, has advanced significantly the past ten years. In particular, advances have been made in visible radiation transmission efficiency with concurrent reductions in fiber size, weight, and cost. Researchers at the Lawrence Livermore National Laboratory (LLNL) coupled these advances in fiber optic technology with analytical fluorescence analysis to establish a new technology - remote fiber fluorimetry (RFF). Laser-based RF… more

Virtually distortion-free imaging system for large field, high resolution lithography using electrons, ions or other particle beams

Description: Virtually distortion free large field high resolution imaging is performed using an imaging system which contains large field distortion or field curvature. A reticle is imaged in one direction through the optical system to form an encoded mask. The encoded mask is then imaged back through the imaging system onto a wafer positioned at the reticle position. Particle beams, including electrons, ions and neutral particles, may be used as well as electromagnetic radiation.

EG&G Film Magazine: Type XPH-47

Description: The EG&G Film Magazine Type XPH-47 was designed to meet specific NC-135 program requirements for a reliable, simple and economical unit which would adapt the LC-4 camera for moving film oscilloscopic photography at film speeds suitable for the separation of oscilloscope sweep traces. Essentially, the XPH-47 is a standard Beattie-Coleman Type 32800 magazine, redesigned for incorporation of features which would fulfill these requirements. One such feature - replacement of the original motor with … more

Development of Structural Neurobiology and Genomics Programs in the Neurogenetic Institute

Description: The purpose of the DOE equipment-only grant was to purchase instrumentation in support of structural biology and genomics core facilities in the Zilkha Neurogenetic Institute (ZNI). The ZNI, a new laboratory facility (125,000 GSF) and a center of excellence at the Keck School of Medicine of USC, was opened in 2003. The goal of the ZNI is to recruit upwards of 30 new faculty investigators engaged in interdisciplinary research programs that will add breadth and depth to existing school strengths … more

Microfluidic System for Solution Array Based Bioassays

Description: The objective of this project is to demonstrate new enabling technology for multiplex biodetection systems that are flexible, miniaturizable, highly automated, low cost, and high performance. It builds on prior successes at LLNL with particle-based solution arrays, such as those used in the Autonomous Pathogen Detection System (APDS) successfully field deployed to multiple locations nationwide. We report the development of a multiplex solution array immunoassay based upon engineered metallic na… more

FABSOAR--A Fabry-Perot Spectrometer for Oxygen A-band Research Final Technical Report

Description: Because this was a Phase I project, it did not add extensively to the body of A-band knowledge. There was no basic research performed on that subject. The principal addition was that a mechanical and optical design for a triple-etalon Fabry-Perot interferometer (FABSOAR) capable of A-band sensing was sketched out and shown to be within readily feasible instrument fabrication parameters. The parameters for the proposed triple-etalon Fabry-Perot were shown to be very similar to existing Fabry-Per… more

ULTRA-HIGH TEMPERATURE SENSORS BASED ON OPTICAL PROPERTY MODULATION AND VIBRATION-TOLERANT INTERFEROMETRY

Description: The goals of the first six months of this project were to lay the foundations for both the SiC front-end optical chip fabrication as well as the free-space laser beam interferometer designs and preliminary tests. In addition, a Phase I goal was to design and experimentally build the high temperature and pressure infrastructure and test systems that will be used in the next 6 months for proposed sensor experimentation and data processing. All these goals have been achieved and are described in d… more

High resolution imaging of vadose zone transport using crosswell radar and seismic methods

Description: The summary and conclusions are that overall the radar and seismic results were excellent. At the time of design of the experiments we did not know how well these two methods could penetrate or resolve the moisture content and structure. It appears that the radar could easily go up to 5, even 10 meters between boreholes at 200 Mhz and even father (up to 20 to 40 m) at 50 Mhz. The seismic results indicate that at several hundred hertz propagation of 20 to 30 meters giving high resolution is poss… more

Measurement of sound velocity in liquid metals

Description: Present techniques for measuring sound velocity in liquid metals have been limited by transducers that cannot survive in extreme temperatures for the long periods these techniques require. The report describes work on a dynamic noncontacting method intended to measure sound velocity in liquid uranium. Measurements were successful with liquid lead, but not with liquid uranium. Flat slab specimens were found to give much better response than cylindrical shapes.

Intra-undulator measurements at VISA FEL

Description: We describe a diagnostics system developed, to measure exponential gain properties and the electron beam dynamics inside the strong focusing 4-m long undulator for the VISA (Visible to Infrared SASE Amplifier) FEL. The technical challenges included working inside the small undulator gap, optimizing the electron beam diagnostics in the high background environment of the spontaneous undulator radiation, multiplexing and transporting the photon beam. Initial results are discussed.

Operator`s manual for the multistation offgas analysis system

Description: The Multistation Offgas Analysis System (MOAS) is a fully automated instrument which can independently measure the gases emitted by up to four samples in containers heated in ovens. A mass spectrometer is used to determine accurately their flow rates. There are six interconnected high vacuum pumping stations, one for each of the sample containers, one for the mass spectrometer, and one for the calibrated leaks which are used to calibrate the mass spectrometer. Quadstar 421{trademark} is the sof… more

Spatially Resolved Spectra From a New X-Ray Imaging Crystal Spectrometer for Measurements of Ion and Electron Temperature Profiles

Description: A new type of high-resolution X-ray imaging crystal spectrometer is being developed to measure ion and electron temperature profiles in tokamak plasmas. The instrument is particularly valuable for diagnosing plasmas with purely Ohmic heating and rf heating, since it does not require the injection of a neutral beam - although it can also be used for the diagnosis of neutral-beam heated plasmas. The spectrometer consists of a spherically bent quartz crystal and a two-dimensional position-sensitiv… more
