The FARCOS frontend electronics.

Castoldi A., Guazzoni C., Parsani T. per la Collaborazione FARCOS
  Venerdì 15/09   15:30 - 18:30   Aula A208   I - Fisica nucleare e subnucleare
In 2017 the first telescopes of FARCOS (Femtoscope ARray for COrrelation and Spectroscopy) will be fully instrumented. Each telescope has 132 readout channels (128 for the Si layers and 4 for CsI(Tl)). The frontend specs are extremely demanding especially in terms of dynamic range and energy resolution. The core of the frontend is the multi-channel charge preamplifier developed in AMS 0.35 $\mu$m technology. A dedicated frontend board houses 2 ASICs and the differential line-drivers to drive the several-meter--long connections. The talk describes the architecture and the performance of the frontend with focus on the experimental qualification of the dynamic range.
