Abstract

A prototype of a readout system developed for high spatial precision tracking detectors at LHC has been tested in a beam at CERN. It is based on a radiation hard CMOS front-end chip which includes signal amplification, storage in an analogue delay line and a deconvolution filter. Data were transferred from the front-end chip using an analogue fibre optic link employing a novel reflective electro-optic modulator and continuous laser light source remote from the detector. This is the first time such a system has been used in an experimental environment and is the basis of the system proposed for the CMS experiment at LHC.
