HIS 14 HD Mono
Monochromatic high density VUV source
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.
The focusing and monochromatizing of the light spot down to 300 μm is realized with state of the art synchrotron beam line optics technology.
Key features
- Dispersive element with
20 % transmission for He I and II - Photon flux
He I: > 1012 Photons/s/mm2 He II: > 1011 Photons/s/mm2 - Spot size < 300 μm
(ø 1.7mm light capillary ) - Ease of operation
- Discharge regulation
- Operating pressure down to
10-10 mbar range
(with 3rd pumping stage)
The HIS 14 HD Mono is mounted on a flange CF 63 ID (optional: CF 100 ID) and comes with a customized adaptor flange to adapt the HIS 14 HD to the customer‘s experiment (chamber drwg. to be provided by the customer).
A low noise digital power supply provides up to 300 mA discharge current for HeI and HeII operation. The minimum photon line width with HeI excitation is below 2 meV. The power supply supports the automatic plasma ignition and the included Pirani pressure gauge.
