General Description
U19 beamline is designed to study magnetic films and bulk samples consisted of 3d states of transition metals (TM) or the 4f states of some rare earth (RE) elements by soft x-ray magnetic circular dichroism. The right- or left-circularity polarized soft x-rays accepted below or above the beam orbit plane are produced by bending magnet and monochromized with a varied line-spacing plane grating (VLSPG) monochromator and refocused by a toroidal mirror.
Beamline optic:
Endstation:
Ultrahigh vacuum chamber with a fast entry
Ultrahigh vacuum chamber with detector of SR light intensity
An electromagnet (up to 1500Gs)
Scientific applications:
SXMCD study of 3d state of TM and 4f of some RE samples
XAS study of elements by X-ray linear radiation
