VUV5000

The VUV5000 is the most intense He-light source on the market. At the same time, it has the narrowest line width. The photon source is based on a He plasma, generated with the ECR (Electron Cyclotron Resonance) technique.

The VUV5000 UV-source includes the following components:

VG SCIENTA VUV5000 UV Source

This is a very high intensity, narrow bandwidth He radiation source with a total VUV flux of more than 2 x 1016 photons/sr s. It includes the VUV5050 source head and the VUV5011 microwave generator. The microwave guide components are also included. The VUV5000 UV-source is optimized for use with the VUV5040 monochromator, but it may also be used stand alone with a capillary VUV light guide to the sample.

Emitted radiation using Helium gas with >99.999% purity:

• 304 Å (41.8135 eV), FWHM < 2 meV (> 10 %)
• 537 Å (23.08 eV), FWHM < 1.2 meV (~ 8 %)
• 584 Å (21.2182 eV), FWHM < 1.2 meV (~ 82 %)

Guarantee:

The VUV5000 UV-source produces 2.0 microA using a 2.8 mm I.D. capillary, -15 V bias and Al photocathode.

VG SCIENTA VUV5051 Differential pumping addition

VUV5050 UV-source head differential pumping addition. The VUV5051 includes both and entrance and an exit capillary in order to maximize the differential pumping efficiency.

VG SCIENTA VUV5056 capillary holder

The Scienta VUV5000-package also includes a fixed VUV5056 capillary holder. A variable version of the VUV5056 is available and can be quoted upon request.
