Synchrotron Summary

NOTE: this is not intended to be an exhaustive summary, this is intended to be a brief summation of the features of some of the beamlines we routinely use.

The Summary Summary

• Brookhaven NSLS beamline X29 - very bright, tunable
• Brookhaven NSLS beamline X25 - very bright, tunable
• Cornell CHESS beamline A1 - bright, fixed wavelength
• Cornell CHESS beamline F1 - bright, fixed wavelength
• Cornell CHESS beamline F2 - moderate, tunable
• Brookhaven NSLS beamline X12C - OK, tunable

More details on X29

• Beamline phone: (631) 344-5629
• Web page: http://www.px.nsls.bnl.gov/x29/x29_info.html
• Source: undulator
• Flux: very bright - 3 x 10¹¹ for (120 um)² at 1.1 Å
• Energy resolution: 3 eV
• Focus: native 120 x 180 microns
• Detector: Quantum Q315 3x3 CCD (3000x3000 binned)
• Goniostat: Crystal Logic kappa, with user click-to-center
• Usable wavelength range: (7-14 keV) from Si(111) monochromator
• Usual exposure ranges: 3-5 seconds per degree.
• Pros: fast, bright, tunable, quick centering
• Cons: radiation damage happens quickly - easy to make mistakes, BNL's network setup user-unfriendly.
• Other: X29 schedule, PXRR home, NSLS home
• Beam: Beam stats, NSLS operating schedule.

• Web page: http://www.px.nsls.bnl.gov/x12c/x12c_info.html
• Source: bending magnet
• Flux: OK - 2 x 10¹⁰ for (200 um)²
• Energy resolution: 3 eV
• Focus: 120 x 180 microns
• Detector: Quantum Q210 2x2 CCD (2000x2000)

• Usual exposure ranges: 30-60 seconds per degree.
• Pros: tunable
• Cons: relatively weak, goniostat was unreliable last time I used it, beam center was unreliable (!!) last time I used it, BNL's network setup user-unfriendly.
• Other: X12C schedule, PXRR home, NSLS home
• Beam: Beam stats, NSLS operating schedule.
