X-Ray Backlighting of Cryogenic Capsule Implosion

2016:

A narrowband crystal imaging system was used to perform x-ray radiography of OMEGA cryogenic capsule implosions (see image above). A 20-ps, 1.5-kJ OMEGA EP laser pulse was used to irradiate a Si x-ray backlighter target located inside the OMEGA target chamber. This configuration made it possible to measure the x-ray absorption of the cold dense shell of DT with 15-µm spatial resolution.

Shown here is a radiograph of a cryogenic implosion
