Thermal equation of state of Molybdenum determined from in situ synchrotron X-ray diffraction with laser-heated diamond anvil cells
Here we report that the equation of state (EOS) of Mo is obtained by an integrated technique of laser-heated DAC and synchrotron X-ray diffraction. The cold compression and thermal expansion of Mo have been measured up to 80 GPa at 300 K, and 92 GPa at 3470 K, respectively. The P-V-T data have been treated with both thermodynamic and Mie-Grüneisen-Debye methods for the thermal EOS inversion. Th...
متن کاملIn situ Raman spectroscopy with laser - heated diamond anvil cells
We have built a micro-optical spectroscopy system coupled with a Nd:YLF laser heating system for performing high pressure–temperature in situ Raman measurements in diamond anvil cells (DAC). A variety of materials can be investigated, providing information about structural and dynamical properties of condensed matter under extreme conditions. We report on a method for laser heating transparent ...
متن کاملIn situ laser heating and radial synchrotron x-ray diffraction in a diamond anvil cell.
We report a first combination of diamond anvil cell radial x-ray diffraction with in situ laser heating. The laser-heating setup of ALS beamline 12.2.2 was modified to allow one-sided heating of a sample in a diamond anvil cell with an 80 W yttrium lithium fluoride laser while probing the sample with radial x-ray diffraction. The diamond anvil cell is placed with its compressional axis vertical...
متن کاملNew Developments On Laser Heated Diamond Anvil Cell
New developments on laser heated diamond anvil cell are reported by introducing a system installed at the Advanced Photon Source (APS). With the system, a laser heating spot of 20 40 μm in diameter can be generated to temperatures over 3000 K for samples in diamond anvil cell; and the temperature gradients in the laser heated volume are less than 100 K. The system is based on the double sided l...
متن کاملSingle Crystal Diamond X-ray Lens Development
The next generation light sources such as diffractionlimited storage rings and high repetition rate free electron lasers (FELs) will generate x-ray beams with significantly increased peak and average brilliance. These future facilities will require x-ray optical components capable of handling large instantaneous and average power densities while tailoring the properties of the x-ray beams for a...
