APS 13-BM-D Diamond Anvil Cell High-Pressure Program
==============================================================

Beamline Overview
~~~~~~~~~~~~~~~~~~~~~~~

The 13-BM-D station uses monochromatic and white X-ray beams from a bending magnet
for X-ray Diffraction measurements on samples at high-pressure in a diamond anvil
cells.  On-line Brillouin scattering allows the simultaneous measurement of X-ray
diffraction and sound velocities.

X-ray Source and Optics
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

13-BM-D uses a portion of the APS bending magnet fan.  White beam can be used for X-ray
diffraction measurements with the multi-anvil press.  A combination of filters (aluminum
and copper) and vertically deflecting mirror can be used for "pink beam" that can be used
for imaging measurements in the multi-anvil press, or for tomography.  Monochromatic beam
from the double-crystal monochromator can also be used for imaging measurements in the
multi-anvil press.



Sample Mounting and Environments

  rotational Drickamer

  T-cup tooling

Typical Paragraph for a publication
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The following includes typical descriptions of the beamline that can
be added to a paper. This is probably more than you need, so feel free
to edit or select portions of this for main text or supplemental
informations as appropriate, or ask the beamline staff for guidance.

This work used the beamline 13-BM-D at the Advanced Photon Source, Argonne National Laboratory.
