UVLS

Versatile and Robust VUV Light Source with Microwave Plasma Generator

The UVLS is a microwave plasma-based UV light source. It is based on a filamentless design and is therefore not subject to the filament ageing of electron impact plasma UV sources. Instead the He plasma is created directly in the quartz output capillary leading to excellent coupling of the generated UV to the chamber or monochromator. This design provides long term plasma stability making the source suitable for use even with heavier gases like Ar and Xe.The source is differentially pumped by an optional available pumping package and is be equipped with dispersing quartz capillary to access medium and large size samples.

MADE FOR THESE METHODS

1

Angle-Resolved Photoelectron Spectroscopy detects the energy and angle distribution of photoelectrons to determine the electronic structure of solids.

APPLICATION NOTES

Small Spot UV Source

Small Spot UV Source

High resolution photoemission measurements demand not only a highest performance electron spectrometer, but also a UV source with high flux density and small spot size, especially for angular resolved studies. SPECS has developed a focused UV source on the basis of the proven technology of the UVS 300 source. Using a special capillary, this source can be focused down to a theoretical spot size of 500 micrometers.

Photoelectron spectroscopy with UVLS and TMM 304

Angle-integrated and angle-resolved photoelectron spectroscopy measurements were performed using the SPECS UVLS ultraviolet-light source in combination with the toroidal-mirror monochromator SPECS TMM304, which was equipped with two cassettes of optical elements in order utilize the HeI and XeI emission lines with photon energies of hν=21.22eV and hν=8.437eV,respectively.
