UPS
Location: Chapman Hall - 030C
Uses:
Allows the user to determine the workfunction and the ionization energy of their sample.
Specifications:The Kratos Axis Ultra DLD is equipped with a helium (He) ultraviolet source allowing for excitation with either the He I ( 21.2 eV) or He II (40.8 eV) lines. Radiation at these wavelengths probes the valence electrons and t he resulting photoelectron spectrum contains a series of peaks each corresponding to valence-region molecular orbital energy levels. The He I source can provide 2,000,000 counts per second at 140 meV resolution on clean polycrystalline silver.
