Non-Destructive Characterization and Evaluation

National Laboratory: 
Lawrence Livermore National Laboratory
Characterization Class: 
Non-destructive examination
Description: 

At Lawrence Livermore National Laboratory’s Non-Destructive Characterization Institute, staff research, design, and build novel systems and methods for government, industry, and academia to understand and help solve their non-destructive characterization (NDC) problems.

Capability Bounds: 

LLNL’s Non-Destructive Engineering (NDE) Group has digital radiographic computed tomographic capabilities that range from a 50-nm spatial resolution and a 16-µm field of view to a high-energy, large-scale system that can provide 200-µm resolution on objects up to 10 m. Ultrasonic NDE capabilities include 3-axis and 5-axis ultrasonic testing (UT) immersion scanning system with adjustable working volumes to 90 cm × 45 cm × 130 cm and scanning resolution on the order of 100s on nm.

Unique Aspects: 

LLNL’s high-energy (6/9 MeV) linear- and area-array radiography detectors can image objects up to 10 m and as small as 30 cm at 8-mm and 200-µm spatial resolution, respectively. LLNL also has access to Advanced Light Source x-ray beamlines at Lawrence Berkeley National Laboratory and the McClelland Nuclear Research Center neutron imaging facility. LLNL’s explosive facilities can accommodate NDC explosive from a few grams up to 160 kg. LLNL also offers a Category 3 nuclear facility to NDC Special Nuclear Materials (SNM).
