The National Ignition Facility is designed to ensure that the U.S. arsenal will work
The target chamber of the National Ignition Facility ( painted blue ) houses a minuscule pellet of plutonium or other materials. Lasers hit the target from all sides, precipitating a fusion reaction. Such experiments enable researchers to gauge the performance of the U.S. nuclear arsenal. (Photograph by Alastair Philip Wiper)
