Title: GAMS4
Description: An instrument called GAMS4, originally designed and built at NIST and now located at Institut Laue Langevin in France, was used in experiments that helped to confirm Einstein's famous equation E=mc². GAMS4 measured the angle at which gamma rays are diffracted by two identical crystals made of atoms separated by a known distance. The two crystals are the dark gray rectangles on circular platforms in the foreground and background of the photo.
