A certain class of experiments foreseen at the European XFEL, could be served very well by 1-dimensional detectors, at least in the beginning. Examples are liquid scattering, or powder diffraction experiments of non-oriented samples, when the scattering pattern is circularly symmetric. Another, very important area where 1-dimensional detectors are of prime importance is for beam diagnostics and beam steering. Currently an inventory of the requirements for the different 1D detectors is being made, with the goal to design a solution that is as generic as possible. A lot of the requirements are similar to the 2-dimensional, it is therefore envisaged that parts of the system, in particular the backend electronics will be common. A schematic layout is given below.
