This portfolio was organized to group innovations that might not be categorized in the other portfolios. Instruments are full systems integrated to perform complex electrical or mechanical work. Sensors are devices that detect, measure, or locate a physical property. Electronics are devices that manipulate electrons or control electrical energy, and the manufacturing processes that fabricate them.

Decades of cutting-edge laser, optics and plasma physics research at Lawrence Livermore National Laboratory (LLNL) played a key role in the underlying science that the semiconductor industry uses to manufacture advanced microprocessors. Now a new research partnership led by LLNL aims to lay the groundwork for the next evolution of extreme ultraviolet (EUV) lithography, centered around a Lab-developed driver system dubbed the Big Aperture Thulium (BAT) laser.
LLNL plasma physicists, Brendan Reagan and Jackson Williams, are the project’s co-lead principal investigators. The project includes scientists from SLAC National Accelerator Laboratory; ASML San Diego; and the Advanced Research Center for Nanolithography (ARCNL), a public-private research center based in the Netherlands.
Funded through DOE’s Unlocking Lasting Transformative Resiliency Advances by Faster Actuation of power Semiconductor Technologies (ULTRAFAST) program, LLNL researchers (in Engineering) will develop an optically-controlled semiconductor transistor to enable future grid control systems to accommodate higher voltage and current than state-of-the-art devices. (Award amount: $3,000,000) while LLNL licensee Opcondys will develop a light-controlled grid protection device to suppress destructive, sudden transient surges on the grid such as those caused by lightning and electromagnetic pulses. (Award amount: $3,178,977)
The Department of Energy’s Technology Transfer Working Group recently awarded two Lawrence Livermore National Laboratory (LLNL) employees with “Best in Class” awards during their May spring meeting in Washington, D.C.
The approach is to use appropriately doped semi-insulating gallium nitride to provide a high damage tolerant photoconductor with high responsivity to various pump wavelength light. Mn, C, or Fe are used as dopants to provide a source of electrons or holes that can be excited. This is combined with the use of dichroic antireflection coating at the GaN/polyimide/liquid crystal…
LLNL researchers have developed a TDLAS-based, standalone, real-time gas analyzer in a small form-factor for continuous or single-point monitoring. The system can analyze multiple gases with ultra-high sensitivity (ppm detection levels) in harsh conditions when utilizing wavelength-modulation spectroscopy (WMS).
LLNL’s novel approach combines 2-color spectroscopy with CRDS, a combination not previously utilized.
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 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…
