R&D Project 1:
An innovative thin microstrip tracking detector system for large-area coverage

Research Objective

Silicon microstrip detectors are ideally suited for low-mass tracking applications as the sensors themselves are thin and passive. In large state-of-the-art tracking systems, however, the material budget from the readout electronics, traditionally attached directly to the microstrip detectors, reduces significantly the advantages of the thin sensors. The goal of this R&D task is to develop the demonstrator of a novel ultra-low-mass microstrip detector module that can be used to build up a light-weight planar tracking station of up to about 1m2 size. We focus on exploring frontier ultra-low-mass Aluminum-Kapton flat-cable technology to route on a very light mechanical support the signals of existing, thin microstrip detectors to fast readout electronics located at the periphery of the module, thus avoiding excessive material budget in the active detector area.
