The experimental hutch of CoSAXS is shown below. There is a beam conditioning unit that contains the incident flux monitor, a set of aluminium filters and a fast shutter. Scatterless and conventional tungsten blade slits are installed to define the beam and remove parasitic scattering.
CoSAXS has the flexibility to install many different sample environments at the sample position. They can either be positioned on a granite block and Z-stage allowing coarse alignment of large sample environments or upon finer translation stages mounted on this granite. Telescopic collimation, based on the design from cSAXS, PSI, will enable the incident vacuum path to be brought as close to the sample environment as possible to reduce air scatter. For some sample environments, through vacuum operation will be possible by connecting directly to the incident collimation and the detector vacuum vessel. Otherwise, X-ray transparent windows, like mica, will be used.
Most sample environments will be remotely controlled and a patch panel is provided to connect motors, thermocouples, serial lines etc.
