Description
The LHCb Silicon Tracker covers a sensitive surface of about 14 m 2 with
silicon micro-strip detectors. It uses up to 132 cm long detector modules
with readout strips of up to 38 cm in length and up to 57 cm long Kapton
interconnects in between sensors and readout chips. This results in large
load capacitances for the front-end amplifiers and an extensive R&D
programme was carried out to demonstrate that good S/N performance can
be achieved despite the fast signal shaping times required for operation at
the LHC. The production of detector modules is coming close to its
completion. Special emphasis has been put on module quality assurance at
all stages of the production. Various tests are performed after each
production step and each module goes through several burn-in cycles lasting
several days each. In my contribution, I will briefly describe the detector
design, give a short overview of the main results from R&D and then
concentrate on our experience from module production and quality
assurance.
