The Fazia initiative: more powerful detectors for a more detailed investigation on the origin and the decay of charged fragments

The main results of the R&D program of the FAZIA collaboration are described. The objective was to improve particle identi???cation capabilities from solid-state telescopes made of Silicon detectors and CsI(Tl) scintillators in view of a new large acceptance apparatus to be used for heavy-ion physics. Important progresses have been made on silicon detectors thanks to a careful control of the material,of its doping uniformity and of the crystal orientation. Moreover,the use of appropriate fast digital electronics allowed to extract maximum information via Pulse Shape Analysis and to propose new con???gurations of CsI(Tl) readout. Some of the recent results of the telescopes are discussed here,together with some perspective and preliminary data on the physics program at intermediate bombarding energies.
