X29 Characteristics
Beamline X29 features high-flux radiation derived from a 54-pole harmonic emission undulator, a vertically focusing mirror and a horizontally focusing monochromator. A Cryomech AL300 is utilized to produce extremely stable cooling on a Si(111) crystal. The beamline is capable of delivering an energy range of 7-14 kev, with resolution and controls suited for Multi-wavelength Anomalous Diffraction. Currently X29 delivers the hottest beam available at the NSLS, followed by X25 which is due to install a new undulator, optics and cooling system over the next year!		Monochromator Si(111) Energy Range 7-14 keV E-Resolution ~ 3 ev Native Focus 0.12 x 0.18 mm Flux at 1.1Å 2.5x1011 ph/s Flux was measured at 1.1Å behind a 120 x 120 um aperture with ring at 2.8 GeV and 300mA.

X29 uses an ADSC Quantum-315, nine quadrant, CCD detector which decreases our total readout time to 2.3 seconds! more on detector

The crystal Logic diffractometer utilizes a kappa rotation to facilitate easier crystal mounts, click-to-center sample alignment, adjustable defining aperture and a detector distance range from 89 to 710mm. more on diffractometer

The X29 Auto-Mounter offers a newly designed LN2 dewer which is thermally improved, mechanically more accurate and features a puck access door on the dewer lid. Loaner tool sets and shipping dewers are available for trial runs. more on automounters
