5-meter Toroidal Grating Monochromator (5m-TGM) Beamline

5-m TGM

 

The beamline is equipped with 3 interchangeable toroidal gratings which cover the photon energies:

25 eV – 60 eV (300 gr/mm)
50 eV – 120 eV (600 gr/mm
100 eV -240 eV (1200 gr/mm)

The resolving power at the Boron K edge (~200 eV) is about 800.

5-m-TGM Surface Science End Station

5m_TGM surface science endstation

The end station for the 5-m-TGM is equipped with:

Omicron EA-125 photoelectron analyzer for UPS (ultraviolet photoelectron spectroscopy) and XPS (X-ray Photoemission Spectroscopy). 
LEED (low energy electron diffraction) optics
sputtering/annealing and thin-film deposition are also available for surface science applications. 
conventional laboratory UV and dual-anode X-ray sources are also available
Soft X-ray absorption spectroscopy (25 eV – 240 eV) can be performed with a total electron yield method.

  • All measurements are done under ultra-high-vacuum (UHV) conditions.
