Ion Sources
Ion Source FDG 15
The high performance fine focus ion source FDG 150 got now a ”little sister”, the differentially pumped ion source FDG 15.
Uses the same proven beam generation as the FDG 150 and can be used as a substitute for all applications where e.g. the wide spread but no longer available ISE 10 (Leybold/Kremer/OMICRON) has been used in the past.
In addition the FDG 15 comes with a more flexible ion optics to adjust for longer working distances and an optional ion flux stabilization.
Ion Source FDG 150
The FDG 150 is an universal UHV Ion Source for depth profile analysis with XPS and Auger Spectroscopy, for sample cleaning, for sensor cleaning in scanning probe microscopes and for charge neutralisation (ESCA). It can also be used as excitation source with ISS/LEIS instruments.
The source is differentially pumped, comes with an integrated port aligner, a regulated leak valve and allows for large working distances.
The power supply offers an integrated scan generator for beam positioning and beam scanning. Furthermore it provides a closed loop regulation of the beam current by controlling of the integrated leak valve.
Photon Sources
High Intensity VUV Source HIS13
The VUV source HIS 13 is a windowless gas discharge light source for the production of VUV light under vacuum conditions.
It can be operated with various discharge gases, such as helium, neon, argon, krypton, xenon or hydrogen. In many applications it is operated with helium in the He I mode delivering a very narrow (1…3meV) emission line at 21.2 eV (584nm) that is commonly used for standard UPS. The pressure rise in the UHV analysis chamber during operation can be below 10-9 mbar.
HIS 14 HD: Focused High Density VUV Source
Designed for ultraviolet photoelectron spectroscopy on solids with the discharge lines of HeI and HeII as well as of other noble gases and hydrogen, the HIS 14 HD is an extended version of the well established FOCUS HIS 13. The small spot of 300 μm makes the HIS 14 HD ideal for ARPES or PEEM applications where high flux densities into a small area are mandatory.
Features: Robust water cooled design with direct-sight connection between the discharge area and the target for easy alignment. A port aligner facilitates the positioning of the light spot on the sample in a range of +/- 3°. For dedicated ARPES experiments there is an optional third pumping stage available for operation in the 10-10 mbar range.
Monochromatic High Density VUV Source HIS 14 HD Mono
The HIS 14 HD Mono has been designed for ultraviolet photoelectron spectroscopy on solids with the monochromatic discharge lines of He I and He II. Together with the small spot of 300 μm the HIS 14 HD Mono is the best choice for ARPES or PEEM applications where high flux densities into a small area are mandatory.
Features: Robust water cooled design with direct-sight connection between the discharge area and the target for easy alignment. A port aligner facilitates the positioning of the light spot on the sample in a range of +/- 3°. For dedicated ARPES experiments there is an optional third pumping stage available for operation in the 10-10 range.
