XCC Facilities

	X-ray Crystallographic Center
	Facilities & Equipment

X-ray Crystallographic Center at University of Maryland expanded significantly (from 2 to 5 diffractometers) and moved to a new lab in Fall 2007. Now the center consists of three labs:
Chemical Crystallography Materials Characterization Protein Crystallography
Chemical Crystallography lab performs single crystal study using Bruker Smart1000 and Apex2 CCD systems:
Bruker Apex2 diffractometer is equipped with:
MoKα sealed X-ray tube
The newest Apex2 CCD area detector for rapid data collection from crystals
Graphite monochromator and Mono cap collimator
Motorized detector to crystal distance from 4 to 15 cm
CryoStream 700 low temperature system working in 80K - 400K range
Integrated Apex2 software suit for integration and advanced data treatment
The Apex2 system, being state-of-the-art, is used in advanced research for crystal structure determination and for handling twinned, disordered and modulated crystals, very small crystals or very large structure and more.
Bruker Smart1000 diffractometer is equipped with:
MoKα sealed X-ray tube (will be converted to CuKα in the nearest future)
Smart1000 CCD area detector for rapid data collection from crystals
Graphite monochromator and Mono cap collimator
Low temperature system (200K and up)
This system, being somewhat outdated, is mainly used for routine room temperature experiments, as training and educational tool and for collaborative research with local universities.
Mounting Crystals
The lab is equipped wide field Leica microscope for crystal selection and mounting
In addition there is available Dry box with microscope/TV system for handling air and humidity sensitive crystals.
Materials Characterization lab employs powder diffraction using Bruker C2 Discover and D8 Advance systems:
C2 Discover with GADDS
CuKα sealed X-ray tube with Göbbel mirror
HiStar (GADDS) detector for real-time data collection, 2D diffractometry and quality patterns from small samples
Parallel beam geometry to probe small areas or regular or irregularly shaped sample
XYZ stage for combinatorial screening; it also allows measuring samples of practically any size
Video microscope with laser alignment for precise sample positioning
Hot stage providing high temperature up to 900 C
D8 Advance with LynxEye and SolX
choice of MoKα, CuKα or even single wavelength CuKβ radiation
SolX and LynxEye (insert) detectors for fast and/or high resolution measurements
9 positions sample changer
ICDD powder diffraction database and search/match software
Advanced TOPAS software for structure refinement

Protein Crystallography lab performs study of macromolecular crystals using Bruker Proteum X8 system:
