Investigation of Equation on State of Matters by Synchrotron Radiation in Combination with Diamond Anvil Cell Techniques

The investigation of equation of state(EOS) for matter under high pressure conditions by synchrotron radiation X-ray diffraction in combination with diamond anvil cell(DAC) are introduced in this paper.Taking lubricant MoS2 as an example,a method of fitting experimental data with Birch-Murnaghan EOS to obtain the bulk modulus of materials is presented.
