The window lies between the sample and the WAXS** detector, a modified, in-vacuum detector, with modules removed to allow scattered radiation to pass through to a SAXS*** detector positioned downstream. The window uses 75um thick Kapton HN film and given the size, pressure and the short distance to the sensors, it was necessary to support it on a frame. To avoid any information loss from shadowing of the detector, a frame was designed so that shadows will be projected into the gaps between the detector modules. The geometry was such that DMLS**** was an effective way of producing the item. Given the slenderness of the structure and the forces it supports, the material approaches or exceeds its yield point, so a bilinear, isotropic, hardening material model was chosen; moreover, large deflections were enabled. Also, the contacts were modelled with augmented Lagrange frictional formulation. All these assumptions made the analysis strongly non-linear.
