E4: The 2-Axis Diffractometer at BER II

Karel Prokes, Fabiano Yokoachiya


The double-axis diffractometer E4 is operated by the Helmholtz-Zentrum Berlin. It is suited for magnetic structure determinations and parametric studies on single crystals in a wide range of external conditions. Pyrolytic graphite and germanium focusing monochromators offer two fixed neutron incident wavelengths of about 1.0*106 ncm-2s-1.
