We present the design and test of a new time-resolved x-ray absorption vacuum chamber, feasible at Synchrotron sources. The instrument will be dedicated to pump-probe experiments in the 100 ps- 100 ns time scale, as achievable at Synchrotron radiation facilities. The dynamical studies in this time scales are crucial in solids and nanostructured systems, for studying structural photo-induced dynamics, phonon-dynamics, shock-waves processes and so on.

The chamber includes a remotely controlled movable mirror that allows to select the optimized collinear or non-collinear geometry of the pump and probe beams and will be connected to the beamline through a valve or a Be window.

Preliminary tests of the probe detector assembling and its efficiency ranging from soft and hard X probe range are in progress.

Pilot experiments on specific nanostructured samples, will be performed at available Synchrotron sources (ELETTRA, SLS, ESRF).

The project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 654360.
