cSAXS is a beamline dedicated to small-angle X-ray scattering (SAXS) and coherent diffractive imaging, in particular ptychography. Located at the Swiss Light Source at the Paul Scherrer Institut in Villigen, Switzerland. For information on experimental setups, geometries, and some sample preparation details see the beamline's endstations website. We strongly encourage all prospective users to discuss their experimental plans prior to proposal submission with the beamline staff

Experiments performed at cSAXS include:

* Ptychographic nanotomography, see for example Shahmoradian et al., Sci. Rep. 7 (2017) 6291Holler et al., Nature 543 (2017) 402. Dedicated instrumentation, which is available to users, is described in Holler et al., Sci. Rep. 4 (2014) 3857Holler et al., Rev. Sci. instrum. 88 (2017) 113701.

* Optics characterization, see for example Vila-Comamala et al., Opt Express 19 (2011) 21333David et al., Sci. Rep. 5 (2015) 7644.

* Small-angle X-ray scattering (SAXS), e.g., Smeulders et al., Nature 478 (2011) 412. SAXS can also be performed with spatial resolution as microscopy technique in 2D (Bunk et al. New J. Phys. 11 (2009) 123016) and in 3D (Liebi et al., Nature 527 (2015) 349). SAXS is also available with time resolution in the millisecond range (Westenhoff et al., Nature Methods (2010) 775) or with a combination of both temporal and spatial resolution (Ibrahimkutty et al., Sci. Rep 5 (2016) 16313).

Preparing for the Experiment

Note that all users participating in the experiment at PSI need to be registered with the PSI Digitial User Office DUO. There, you will find important functionalities for managing your experiment at PSI, including the mandatory application for badge and dosimeter, and information in regard to guest house reservation, shipping instructions, etc.

Please note that it is the main proposer's responsibility to disseminate information to collaborators.
