PHELIX is a beamline using soft X-rays, the source of which is an APPLE II undulator with permanent magnets.
This type of insertion device gives the opportunity to obtain a variable polarization of light: linear polarization at any angle as well as circular and elliptical polarization.
The PHELIX end-station enables a wide range of spectroscopic and absorption studies characterized by different surface sensitivity. Besides collecting standard high-resolution spectra, it allows, e.g. to map the band structure in three dimensions and to detect the spin in three dimensions.
The main components of the PHELIX end-station are as follows:
Parameters: | Value: |
---|---|
Radiation source | elliptically polarizing undulator (EPU), APPLE II type with permanent magnets |
Photon energy range (using the energy of the electrons in the storage ring of 1.5 GeV |
50–1500 eV for linear horizontal, linear vertical, and circular polarization |
Maximum resolving power | > 10 000 |
The maximum size of the excited area on the sample | 100 µm x 100 µm with the resolving power (RP) ≥ 10 000 over the entire energy range and for all polarizations |
Photon flux on the sample | ≥ 1×1013 photons/s/0.1% B.W. for 50 eV and ≥ 1×1011 photons/s/0.1% B.W. for 1500 eV, for maximum RP and electron current in the storage ring (500 mA) |
Controlled polarization | variable linear, circular and elliptical |
Available techniques | PES (ResPES, ARPES, SX-ARPES, SR-ARPES, XPS, UPS, CD-ARPES), XAS (TFY, TEY) |
