The design of a dynamical sagital-focusing monochromator for hard X-rays (6-60keV) is described. The monochromator consists of two crystals in a pseudo channel-cut arrangement. The first is a mini-channel water-cooled flat crystal. The second is a diamond-shaped ribbed crystal which is clamped by its reinforced central rib. It is bent by applying a force at its apices, allowing radiation of up to 60 keV to be focused. Integrated into the crystal bender mechanism are two actuators that allow the removal of twist in the crystal as it is bent. The monochromator is routinely used in multiple-anomalous scattering studies of macromolecular systems. © 2000 American Institute of Physics.

    MAX-lab has introduced a local perturbation to the electron orbit of the MAX II storage ring, providing users at the SX700 monochromator beam line, D1011, with elliptically polarised soft x-rays. This is achieved by using corrector magnets to send the electron orbit on an ascending or descending...
