Rugged, power-efficient and compact system based on TDLAS for remote sensing of multiple gases in challenging environments

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).

Trace Gas Detection with 2P3C Ring-Down Spectroscopy

LLNL’s novel approach combines 2-color spectroscopy with CRDS, a combination not previously utilized.

Computer designed bridge
Development of an Application Programming Interface (API) to merge Computer Aided Design (CAD) software and Livermore Design Optimization (LiDO) code

The LiDO code combines finite element analysis, design sensitivity analysis and nonlinear programming in a High-Performance Computing (HPC) environment that enables the solution of large-scale structural optimization problems in a computationally efficient manner. Currently, the code uses topology optimization strategies in which a given material is optimally distributed throughout the domain…
