The research activity lies in the framework of the INFN experiment EXOCHIM, and consists of the development of an innovative high dynamic range front-end electronics to be coupled with the silicon microstrip detectors used as first and second detection layers in the FARCOS telescopes. Such telescopes ¿ featuring a high degree of granularity ¿ are designed for Light Charged Particles and Intermediate Mass Fragments correlation measurements in middle-energy (10-100MeV) collision experiments.
The work-program schedules the design and implementation of a dedicated VLSI front-end electronics able to perform pulse shape discrimination in a wide energy and particle range and coping with the requirements imposed by the digitization of the whole waveform. The request of a high dynamic range imposes to explore different architectures of the front-end based both on the voltage-mode and on the current-mode approach. A theoretical investigation ¿ based on calculation on simplified models and 3D simulations ¿ aimed at finding the best performing parameters for particle identification will complement the design and characterization effort. Last but not least the research program will include the detailed characterization of the developed front-end coupled with the microstrip detectors in dedicated test beams and in true on-beam experiments.
It is also planned a strong interaction with other Italian and foreign institutes, as the Laboratori Nazionali del Sud in Catania, the Ganil laboratory and the Service de Physique Nucléaire, IRFU, CEA in France.
