Status and perspective of FARCOS: A new correlator array for nuclear reaction studies

The experimental investigation of Heavy Ion reactions at Fermi energies requires an accurate measurement of observables, such as linear momentum and energy of the detected particles. In order to address this problem, dedicated and flexible correlator arrays are useful tools to be coupled with 4π detectors. One of these arrays is FARCOS (Femtoscope Array for Correlation and Spectroscopy), presently under construction. FARCOS is a modular array of telescopes arranged in a single cluster, each one consisting of 3 detection stages. The first two stages are two Double Sided Silicon Strip Detectors (DSSSD) of active area 6.4*6.4 cm² with 32 vertical strips in the front side and 32 horizontal strips in the back side and are 300 μm and 1500 μm thick respectively. The last stage consists of four CsI(Tl) crystals (3.2 * 3.2 cm²) of 6 cm of thickness read by a photodiode (18 * 18 mm²). We have tested performances of four clusters of the FARCOS prototype. The obtained results are quite satisfactory and fit the requirements for new generation correlators for charged light particles and fragments, in heavy ion physics at intermediate energies. On 2015 year the FARCOS prototype will be used in two experiments at LNS, i.e., CLIR and SIKO
