Spectral Range

15-250 eV

An Elliptical Polarized Undulator provides an intense beam in the 15-250 eV energy range with user-specified polarization (varying from linear polarization to circular polarization). Please contact VLS-PGM staff to discuss your specific experiment needs.



VLS-PGM supports material samples in a variety of forms, including thin films, pressed pellets, metal chunks, and powders. The sample size should be kept to a minimim, with the maximum size not exceeding 10mm x 10 mm in area and must be stable in ultra high vacuum. VLS-PGM offers some sample temperature control. Please contact VLS-PGM staff to discuss your specific experiment needs.

Detailed sample powder preparation information is available on the VLS-PGM user guide.
