13 BMD Multi-anvil Press (LVP)         

The 250T large volume press (LVP) houses our DIA, D-DIA, HPXMT, and T-10 pressure modules. By combining X-ray diffraction and imaging techniques with these high-pressure modules, our facility provides a unique “Swiss-army-knife” approach to solving scientific problems with optimal flexibility.

Beamline Optics

The bending magnet fan is divided into two parts.   An outboard fan of 2.5 mrad feeds the 13-BM-D station, and an inboard fan of 1.5 mrad feeds the 13-BM-C station.   These fans are separated  by 1 mrad. The extreme inside and outside 0.5 mrad on each edge of the 6 mrad fan is not used.

The 13-BM-D beamline has a non-focusing Si <111> double crystal monochromator that covers the energy range from ~5 to 70 keV.  There is a 1 m long vertical focusing mirror in the 13-BM-B optics station.  This mirror is used for some experiments and removed for others.  There are small K/B mirrors that are placed on the experimental table in 13 BM-D.
