Experimental Station 11-3

Beam line 11-3 is a fixed energy (12.7 keV) wiggler side-station dedicated primarily for wide angle x-ray scattering (WAXS). BL11-3 is equipped with a two-dimensional Rayonix MX225 CCD area detector. Supports sample-to-detector distances of 80-550 mm. There are sample environments available for both transmission and grazing incidence geometries. Sample heating is available for both single sample transmission and grazing incidence geometries.
