PETRA III Science Seminar | P66: first year of user run

by Yevheniia Smortsova (DESY)

Tuesday 9 May 2023, 14:15 → 15:00 Europe/Berlin

Virtual

The user operation run at the P66 beamline at PETRA III started in the end of the year 2021 [1]. The P66 beamline is operating in the UV- VUV spectral region (1-40 eV) with the temporal resolution down to tens of picoseconds. P66 inherit many parameters from the SUPERLUMI beamline at the DORIS synchrotron [2]. VUV time-resolved luminescence spectroscopy (TRLS) with pulsed synchrotron source excitation is a very sensitive and non- destructive method of probing solid-state materials in ultrahigh vacuum (UHV) conditions. Very few places in the world would offer an option to provide VUV-TRLS experiments, and among them, P66 is standing out, outclassing the competition within a row of important characteristics.

            A short description of the P66 beamline key parameters, commissioning as well as scientific results will be presented. Upcoming investigation on TRLS and polarization experiments will be discussed as well.
