To solve these challenges using new and existing CT system designs, LLNL has developed an innovative software package for CT data processing and reconstruction. Livermore Tomography Tools (LTT) is a modern integrated software package that includes all aspects of CT modeling, simulation, reconstruction, and analysis algorithms based on the latest research in the field. LTT contains the most…

LLNL's 3D X-ray imager combines two different hardware pieces. The first is an x-ray optic with a depth-of-field that is small compared to the object under investigation. Reflective Wolter type x-ray optics are one such design. These hollow optics have a relatively large collection efficiency and can be designed with a large field of view. The depth of focus, which is the distance over which a…

LLNL researchers have developed a broadband heterodyne detection system that incorporates several significant improvements that move the state of the art toward quantum noise limited performance. The design comprises of an optical element that increases the intensity of the incoming light on the detector by a factor exceeding 50x. It is based on the properties of surface plasmons in…

LLNL researchers have designed and tested performance characteristics for a multichannel pyrometer that works in the NIR from 1200 to 2000 nm. A single datapoint without averaging can be acquired in 14 microseconds (sampling rate of 70,000/s). In conjunction with a diamond anvil cell, the system still works down to about 830K.

LLNL's method of equivalent time sampling incorporates an embedded system that generates the pulses used to trigger the external circuit and the data acquisition (DAQ). This removes the external reference clock, allowing the overall system clock rate to change based on the ability of the embedded system. The time delays needed to create the time stepping for equivalent time sampling is done by…

This invention suggests to reduce the noise in Q-bits and other low-noise electronic and superconducting devises devices by synthesizing special materials where several classes of fluctuators (two-level systems) are excluded (or, their number is substantially reduced) both in the volume of materials and on the boundaries and interfaces. This invention also suggests materials with low number of…

A key element of this invention is the recognition that all life-important chemical interaction is situated in the mid-to-far infrared energy range. LLNL’s Infrared (IR) Photon-Sensitive Spectromicroscopy invention is a system designed to suppress thermal radiation background and to allow IR single photon-sensitive spectromicroscopy of small samples by using absorption, reflection, and…

The LLNL approach uses both the electric and magnetic components of an electromagnetic wave, which provides information about the direction of wave emanation as well as the flux of energy in the wave. This new, potentially portable technology is intended to identify and locate low-frequency electromagnetic noise sources in order to take off-line or quickly isolate and repair the interfering…

LLNL's high fidelity hydrocode is capable of predicting blast loads and directly coupling those loads to structures to predict a mechanical response. By combining this code and our expertise in modeling blast-structure interaction and damage, along with our access to experimental data and testing facilities, we can contribute to the design of protective equipment that can better mitigate the…

The Forensic Science Center at LLNL has invented a portable, compact and rugged hydrogen peroxide vapor generator. The system produces a consistent concentration of hydrogen peroxide vapor. The hydrogen peroxide vapor is generated from a safe and easy to maintain source of aqueous hydrogen peroxide and produces a dynamic flow stream at discrete concentrations.
