New end-station for time- and angle-resolved photoelectron spectroscopy in Artemis facility — •Yu Zhang, Charlotte E. Sanders, Bruce Weaver, Tiffany Walmsley, James O. F. Thompson, Richard T. Chapman, and Emma Springate — Central Laser Facility, STFC Rutherford Appleton Laboratory, Research Complex at Harwell, Harwell, United Kingdom

Artemis, located at the Central Laser Facility in the UK, is a user facility offering time- and angle-resolved photoelectron spectroscopy (TrARPES) utilizing extreme ultraviolet (20-45 eV) photon sources based on high harmonic generation of ultrafast laser. After more than a decade of operation, Artemis has established itself as a leading facility in the research of ultrafast electron dynamics on surfaces. Recently, Artemis received an significant upgrade of its end-station, which will provide users with state-of-the-art techniques in ultrafast time-resolved measurements. These new capabilities include both momentum and real-space mapping, large-angle E-k mapping with a deflector, and a closed-loop cryostat for low-temperature measurements. Detailed information about these features can be found in the poster. Along with the recently upgraded 100kHz laser source, Artemis is committed to delivering high-performance TrARPES for its user communities.
