An illustration showing the NNSA logo and the word X-RAY, in the middle is a whimsical black-and-white illustration of a skeleton holding a beaker. The skeleton is wearing protective goggles and a bowtie. The bottom of the illustration shows where X-rays appear in the electromagnetic spectrum.
X-rays are vital tools at NNSA. They help scientists study how plutonium ages and explore how inertial confinement fusion works.
The spectrum of NNSA work
At NNSA’s labs, plants, and sites, research supporting our vital missions reaches across the electromagnetic spectrum – from radio waves to gamma rays. Sometimes that innovation spills into other areas, too, enabling tomorrow’s technological wonders.
NNSA completed the Last Production Unit (LPU) of the B61-12 Life Extension Program (LEP). The B61-12 is the latest modification to the B61 family of gravity bombs, which are deployed from U.S. Air Force and North Atlantic Treaty Organization bases.
