Ultrahigh Pressure: Beyond 2 Megabars and the Ruby Fluorescence Scale

P. M. BELL 1, H. K. MAO 1, and K. GOETTEL 1

1 Geophysical Laboratory, Carnegie Institution of Washington, Washington, D.C. 20008

A new design of the diamond-window, high-pressure cell has permitted static pressure of 2.8 megabars to be generated for the first time. The design is unusually stable mechanically, and thus it should be possible to use the new cell to study most materials, including hydrogen, in the unexplored pressure region above 1 megabar.
