PINK

PINK@EMIL

The PINK branch is operated in the tender x-ray energy range (2.1 - 10 keV) providing access to non-resonant / resonant XES studies of transition metals ranging from Ti to Cu (Kα, Kβ lines) and Zr to Ag (Lα, Lβ lines), as well as light elements P, S, Cl, K, Ca (Kα, Kβ lines). A multilayer monochromator provides the high photon flux allowing measurements of very diluted substances. Taking advantage of a wavelength-dispersive von Hamos analyzer to record the entire fluorescent spectrum simultaneously, we can provide very attractive time-resolved XES measurements.

The PINK instrument is located at the hard (2000 eV – 10000 eV) x-ray branch of the EMIL beamline.

Selected Applications:
  • homo- and heterogeneous catalysis
  • electrochemistry
