Optics: 13-BM-D is served by a sagittally focusing low-energy and high energy monochromators (both in 13-BM-A).

Instrumentation: 13-BM-D is a general purpose station used for spectroscopy, XRF microprobe, diffraction, and tomography experiments. The diffraction experiments will include high-pressure experiments in the diamond-anvil cell and the large-volume press, possibly a small multi-anvil.

Experimental Station 13-BM-C

This station is used primarily for diffraction experiments in the 7.5-20 keV energy range. A general purpose diffractometer is planned.

Optics: 13-BM-C is served by a conical mirror (in 13-BM-A) and a single bounce, horizontally focusing monochromator. Instrumentation: 13-BM-C is used primarily for diffraction experiments in the 7.5 to 20 keV energy range.

Insertion Device Beamline

The ID beamline has two optics enclosures (13-ID-A and 13-ID-B) and two tandem experimental stations (13-ID-C and 13-ID-D). A standard Undulator A has been installed and will be used in both untapered and tapered modes. Cryogenically-cooled Si monochromators (13-ID-A) will include a "low-energy" monochromator for use in the 3.5-21 keV range, and a "high-energy" monochromator for use in the 15-80 keV range

Optics : Cryogenically-cooled Si monochromators (13-ID-A) : a "low energy" monochromator for use in the 4.5 to 21 keV range, and a "high" energy monochromator for use in the 15 to 80 keV range. The first crystal on the low energy monochromator is thin, and the transmitted beam can be used directly or with the high-energy monochromator. Thus, these monochromators can be used simultaneously. Power management aperture (13-ID-A) limits the total white beam power which can leave 13-ID-A to less than 100 W at 100 mA operation with the undulator at closed gap (10.5 mm). Kirkpatrick-Baez mirrors (13-ID-B) : Two, ~1 m long Si mirrors for focusing either white or monochromatic radiation within the two experimental stations (demagnification = 10:1 to 3:1). Deflecting crystal (13-ID-B) deflects the low energy monochromatic beam sideways into the 13-ID-C station, permitting simultaneous operation of 13-ID-C and 13-ID-D for certain combinations of experiments.

Experimental Station 13-ID-C

X-ray absorption fine structure spectroscopy, microprobe, angle-dispersive diffraction, microcrystal diffraction, and tomography using the low energy or high energy monochromators; focused and unfocused white-beam mode for energy-dispersive diffraction in the diamond anvil cell and for XRF microprobe experiments.

Energy-dispersive diffraction experiments in the large-volume press, using focused or unfocused white-light from the tapered undulator; monochromatic diffraction experiments in the DAC and LVP using beam from the untapered undulator with the high energy monochromator.

1000 metric ton hydraulic press manufactured by Rockland Research. Maximum hydraulic pressure is 10,000 psi. A similar press with improved structural design (greater safety factor to yield) is being manufactured and will be installed in 13-ID-D.

Double sided laser heated diamond cell for in-situ high P-T diffraction study. The double-sided heating approach allows one to combine different lasing modes to optimize temperature uniformity. The laser heating apparatus is set-up and running in 13 ID-D.
