P61 High Energy wiggler beamline/LVP

P61 is under commissioning | Large Volume Press (LVP) can be used online and offline

The X-ray source of beamline P61 is an array of ten 4m long fixed-gap damping wigglers which serve to reduce the machine emittance. The powerful white beam from these insertion devices will be filtered by an absorber unit to reduce the total power load on the downstream optical elements. Essentially, the low-energy part of the spectrum (below about 40 keV) will be cut off. However, still more than 50% of the total emitted power will still present in the high-energy spectrum. The beam size will be adjusted by a high-power slit system in an optics hutch. The filtered white beam (“pink” beam) will then be guided to the experimental hutches downstream which will employ energy dispersive X-ray techniques initially.

In the first hutch, Helmholtz Center Geesthacht (HZG) has instrumentation focused on materials science and engineering applications using energy dispersive X-ray techniques. Applications include surface diffraction using "Laplace space" methods or transmission diffraction with gauge volume control.

In the downstrem hutch DESY will operate a large-volume press instrument (LVP) for studies of materials under extreme conditions. The instrument can already be used off-line for materials synthesis.

The LVP can be used offline - without X-rays. Users are encouraged to prepare experiments as much as possible in advance and bring anvils with common truncation edge length (TEL). Notwithstanding, we can fully accommodate you in our sample preparation laboratory if you have no resources except for the sample you wish to synthesise at high P,T conditions. Please contact Robert Farla if you are interested in perfoming LVP experiments.
