PINK

PINK@EMIL

The PINK branch is operated in the tender x-rays 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 dilute 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.

Selected Applications:
  • homo- and heterogeneous catalysis
  • electrochemistry
