Soft X-Ray Scattering End Station

This end station has been specially engineered to solve the problem of the limited optical access typically associated with magnetic fields and synchrotron radiation measurement stations. An octupole magnet provides a fully variable direction vector field. A cryogenically cooled manipulation transfer system is provides the necessary flexibility to address a wide variety of magnetic samples. The whole system is ultra high vacuum compatible with a base pressure of 5 × 10 ^-10 mbar. The eight water-cooled magnets, spaced equidistantly over the surface of a sphere, allow the application of the field in any direction. These high current magnets generate a field in the area of the sample of 1T. A photodiode detector travels along a +/- 90 [deg] arc perpendicular to the beam axis. This motion, coupled with the entire system rotation of +/- 90 [deg] and incoming light polarization allows for the diode to be placed anywhere on a hemisphere perpendicular to the beam for any light polarization. The system also has provisions for cooling the sample with LHe and sample positioning in X, Y, Z, and rotation about the Z axis with micron resolution.
