Beamline 21-ID-D: Insertion Device Beamline

Description

Sector 21 uses canted undulators to provide two independent sources for four ID end stations: 21-ID-D, 21-ID-E, 21-ID-F, and 21-ID-G. All four stations can be used simultaneously and independently. The 21-ID-D station supports macromolecular crystallography, SAD and MAD phasing over a wide energy range from 6.5 keV to 20 keV. All LS-CAT experimental stations are equipped with MD-2 diffractometers with state-of-the-art features such as on-axis sample viewing with precision zoom, automatic sample alignment, omega/kappa/phi motions, and a tuned piezoelectric fast shutter.

Supported Techniques

• Macromolecular crystallography
• Microfluorescence (hard x-ray)
• Nano-fluorescence imaging
• Nano-tomography

Beamline Controls and Data Acquisition

MD-2 diffractometer software from EMBL (with LS-CAT developed extensions) for sample mounting, centering, beamline diagnostics, and data colection. VME EPICS/MEDM low-level interface, PMAC Turbo motion control, and Linus workstations for data collection and processing.

Detectors

• Mar 300 CCD
• Bruker-AXS XFlash 1001 SSD for fluorescence spectroscopy

Additional Equipment

• CATS Sample Changer: SPINE or ACTOR pucks
• MD2 Micro Diffractometer
