Description
The PLUME (Pixelated Ladder with Ultra-low Material Embedded) collaboration is developing ultra light ladder for the vertex detector of a future linear collider. This object is a double-sided detector which integrates thin pixelated sensors (50 µm), readout infrastructure and mechanical structures aiming at an overall material budget about 0.3% X0.
Both the thinning and the gluing process of the sensors generate inevitable non-flatness of the detection surface. These deformations impact the spatial resolution in certain circumstances.
The fist prototype ladders were prepared and tested in the SPS beam in 2011 at CERN. We will present the analysis results of the test beam data quantifying the shape deformation and a correction method to recover the genuine spatial resolution.
