PETRA III at DESY
P01 High-Resolution Dynamics

 

P01 is dedicated to Nuclear Resonant (NRS) and Inelastic X-ray scattering (IXS) experiments at photon energies between 2.5 keV and 90 keV. The beamline offers high energy resolution monochromators in the range from 1 meV to about 1eV and high spatial resolution in the (sub-)micron regime. Beamtime applications for NRS are accepted since November 2011. Proposals for Inelastic X-ray Scattering (IXS) are accepted since June 2014.

Since 2016, the Max-Planck-Gesellschaft (MPG) is shareholder of the P01 beamline for 40 % of the total beamtime. The MPG research is part of the IXS program and shared equally between two groups from the Max-Planck-Institut Dresden (Prof. Hao Tjeng) and the Max-Planck-Institut Stuttgart (Prof. Bernhard Keimer).

Contacting the beamline staff in case of uncertainties concerning the feasibility of the proposed experiments is highly recommended.

 

P01 provides different sample environments:

- diamond anvil cells for high pressure experiments

- closed cycle cryostats, T range from 6 K to 800 K

- a He bath cryostat, T range from 3 K to 300 K

- a cryostream setup for 400 K > T > 80 K

- different ovens T up to 1500 K

- an electromagnet for B fields up 1 Tesla

- a cryo vector- magnet system with max. field of 6 Tesla in beam direction and 2 Tesla in arb. direction and a minimal sample temperature of about 2 K.

- an in-situ sputter deposition chamber

 

NRS studies on 57Fe, 119Sn, 121Sb, 125Te and 193Ir are performed rutinely other isotopes are also possible.

The X-ray Raman Scattering spectrometer is using Si (nn0) analyzers. The incoming resolution can be chosen between the one from a Si (111) or Si (311) crystal set.

 

The RIXS setup (still in the commissioning phase) is dedicated to Ru L3-edge measurements at 2.840 keV with a total resolution of 100 meV.

Work on improving the high resolution monochromator and the analyzer scheme for even better resolution is in progress.
