Status

Open without synchrotron radiation

Expected status of the facilities for the next half year (updated 2024-08-01). Availability of facilities subject to change without notice for technical reasons. Please ask if you have specific requirements.

As the SLS is undergoing a major upgrade since October 2023, no synchrotron light is available at PEARL until the new beamline opens in 2026. In the meantime, the PEARL endstation (sample preparation, STM, XPS/ARPES with lab source) remains operational. Please ask beamline staff if you have any requests for experiments at PEARL.
