Beamlines

The following is a list of x-ray scattering beamlines available to the user community:

Available Synchrotron Beamlines

Beamline	Facility	Status	Description	Techniques	Energy range	q-range	Access
X9	NSLS at BNL	Running until Sept. 2014	X9 is an undulator-based (high-flux) and high-resolution beamline that can perform transmission and grazing-incidence scattering across a wide q-range (simultaneous SAXS/WAXS possible). Typical beam size is 150 µm for TSAXS and 50 µm for GISAXS (focus to ~15 µm is possible). Measurements in air or vaccum are possible. Sample environments for performing in-situ sample heating (RT-220°C for GISAXS, RT-80°C for TSAXS) are available. Accomodations for in-situ experiments (solvent annealing, electrochemical cells) are also possible.	SAXS, WAXS, GISAXS, GIWAXS	6 keV to 20 keV	0.002 Å−1 to 4.2 Å−1	Through NSLS or CFN user programs. (No longer accepting proposals.)

Available Labscale Instruments

Instrument	Facility	Status	Description	Techniques	Energy range	q-range	Access
Bruker Nanostar	CFN at BNL	Available to users.	This labscale rotating-anode instrument is available to users. Of course a labscale instrument will not have the flux or resolution of a synchrotron beamline; nevertheless this instrument is optimized for resolution, while providing sufficient flux for measuring strongly scattering systems (e.g. nanoparticles). The sample environment is under vacuum, and offers both transmission-mode and grazing-incidence stages. Contact Dmytro Nykypanchuk or Kevin Yager for details.	SAXS, WAXS, GISAXS, GIWAXS	8.04 keV	0.005 Å−1 to 0.3 Å−1 (up to ~2 Å−1 using image plate).	Available through CFN user program.

Future Synchrotron Beamlines

Beamline	Facility	Status	Description	Techniques	Energy range	q-range	Access
CMS	NSLS-II at BNL	Under construction.	CMS is an bending-magnet beamline being constructed at NSLS-II, based in part on the design and hardware at X9 (NSLS). The beamline will be able to perform transmission and grazing-incidence scattering across a wide q-range (simultaneous SAXS/WAXS possible), and will emphasize automation, high-throughput, and in-situ measurements.	SAXS, WAXS, GISAXS, GIWAXS	10 keV to 17 keV	0.002 Å−1 to 4.2 Å−1	Will be available through NSLS-II user program.
SMI	NSLS-II at BNL	Under construction.	SMI is a undulator-based beamline being constructed at NSLS-II. SMI will be a high-flux and high-resolution instrument optimized for grazing-incidence measurements on interfaces, though also capable of performing world-class transmission scattering experiments.	SAXS, WAXS, GISAXS, GIWAXS, XR	~2 keV to 24 keV	Very wide q-range (SAXS and WAXS).	Will be available through NSLS-II user program.
