E6
Focusing Powder Diffractometer
E6 uses a horizontally and vertically bent monochromator [1] and an in-pile fan collimator [2, 3]. The fan collimator imitats a vertical slit with adjustable distance to the monochromator. This diffraction geometry achieves a focusing in reciprocal space. At medium resolution, the neutron flux is increased by a factor of two compared with diffractometers that use standard Soller collimators.
