Description
An upgrade of the LHC towards a 10 times higher luminosity will require tracking detectors with unprecedented radiation tolerance. Furthermore, the high track density will call for fast and high granularity detectors, which also fulfill the boundary conditions of low radiation length and low costs. Over the last years several promising material developments and design concepts for the next generation of silicon pixel detectors have been brought forward.
In the framework of Pixel Sensors R&D at CERN the noise and signal behavior for different sensor types has been studied with the goal of optimizing detector layout for their signal-to-threshold performance. The study included planar silicon sensors, 3D silicon sensors of different layout and manufactured by different producers as well as CVD diamond sensors. Details about the test results including for example comparative noise studies for different sensor types will be presented. Particular emphasis will be put on testing novel 3D-DDTC (Double side Double Type Columns) sensors produced by FBK/irst.
