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.

Techniques
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.

Access
Purchased Access
Purchased access offers quick and accurate solutions to proprietary questions. CLS scientists develop experimental plans based on clients' needs, collect and analyze data, and provide detailed reports with key answers to critical questions.
Peer-Reviewed Access
Academic clients can submit proposals through a peer review process. Beam time is granted based on scientific merit, with the expectation that any results will be published. In special cases, rapid access is also available for instrument or beam time.
