VLS-PGM - Variable Line Spacing Plane Grating Monochromator Beamline

Facilitating research in materials of both fundamental and applied nature, the VLS-PGM beamline provides high resolution, low energy spectroscopic studies. We invite users and collaborators to discuss their proposal with the Beamline Staff before submission. This is crucial for a careful assessment of the experiment feasibility.

Samples

Users at VLS-PGM are provided with sample holders at the beamline, and tools to properly mount their sample using available CLS laboratory facilities. Up to three sample holders can be loaded in the pre-chamber, with one holder at a time in the main chamber. Detailed sample preparation information is available on the VLS-PGM user guide.
