Direct Compression Measurement of Imploded Targets

1977:

The first direct measurement of compressed fuel density in a laser-imploded target using x-ray spectroscopy is reported in a Physical Review Letters article by LLE scientist B. Yaakobi, et al.

Shown here is a compression measurement from the article, B. Yaakobi, D. Steel, E. Thorsos, A. Hauer, and B. Perry, “Direct Measurement of Compression of Laser-Imploded Targets Using X-Ray Spectroscopy,” Phys. Rev. Lett. 39 241526–1529 (1977).
