Status
Expected status of the facilities for the next half year (updated 2023-08-01). 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 starting October 2023, no synchrotron light will be available at PEARL until the new QUEST beamline opens in 2026. The PEARL endstation (sample preparation, STM, ARPES with lab source) will remain operational in the mean time. Please ask beamline staff if you have any requests for experiments at PEARL.
