Cross-section of the target chamber in an artist’s concept of an inertial fusion energy power plant
Additively manufactured targets for inertial confinement fusion

LLNL researchers have developed additive manufactured fuel targets for IFE.  They have been successful in using TPL to fabricate low density (down to 60 mg/cm3) and low atomic number (CHO) polymeric foams for potential targets, and some have been tested at the OMEGA Laser Facility. With TPL, LLNL researchers have also been able to fabricate a full fuel capsule with diameter of ~ 5mm or…

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).

Devices for precision uniform coating of rolling spheres used as inertial fusion energy targets

This invention configures multiple spherical substrate targets to roll independently of one another.  The spheres’ rolling motion is deliberately randomized to promote uniform coating while eliminating the interaction (rubbing, sliding) of adjacent spheres that is present in conventional sphere coating designs. The devices’ novel structure features enable the collimation of depositing…
