The Complex Materials Scattering (CMS, 11-BM at NSLS-II) beamline can support a wide range of sample environments. The sample chamber can be operated in ambient atmosphere (air), or under vacuum.
Contents
Typical
Capillary Holder
CMS has capillary holders that can hold 15 capillaries each. The holders are on universal (magnetic/kinematic) bases, allowing very rapid swapping between holders.
Heated Capillary Holder
An alternate bracket for the capillary holder allows heating of the samples. The holder can reach ~220C in vacuum, and at least 100C when operated in air.
GISAXS Bar
A simple bar allows multiple (~10) thin film samples on substrates to be loaded at once. Each sample can be measured by translating the setup sideways. The bars are affixed to universal bases (magnetic/kinematic), allowing rapid switching of samples.
The GISAXS bars are ~110 mm (4.3 inches) long (across the beam), and 25.4 mm (1 inch) wide (along the beam direction). The 110 mm width means that one can typically fit about 10 samples (where each is 1cm in size). The stage motion in this direction has a travel range of 150 mm; thus samples can be positioned right up to the edges of the bar.
Heated GISAXS Bar
The heated GISAXS bar allows multiple samples to be heated together. The holder can reach ~250C in vacuum.
Customized
Specialized sample environments can be created on an ad-hoc basis. Please contact beamline staff to discuss this possibility well ahead of any beamtime.
Sample rotation
Rotation stages can be used to align and rotate samples (e.g. for CDSAXS).
Stretching
As an example, the motion positioning stages can be used as a crude tensile/stretching setup:
User Supplied
CMS can accommodate a wide range of user-supplied sample environments. For instance, users have brought specialized heated stages, tensile/stretching stages, and customized in-situ film deposition systems.
