“…High resolution imaging techniques -together with the measurement of the reciprocal correlations of the reaction products -can provide a sort of "space-time" snapshots of particles and complex fragments emitting sources [1]. Hodoscopes of silicon and scintillator crystals have become a typical detector array covering a reduced angular region in the reaction chamber.…”

We are currently developing a novel detection system, named FARCOS (Femtoscope Array for Correlation and Spectroscopy) and featuring high angular and energy resolution and able to reconstruct particle's momentum at high precision for different physical cases in multi-fragmentation nuclear physics experiments. Performing a Pulse Shape Analysis on signals coming from the ΔE stages -Double Sided Silicon Strip Detectors (DSSSDs) -we aim at identifying in charge and mass even particles stopping in the first detection layer. In the framework of the full characterization of the DSSSD response in terms of both the linearity of the amplitude response and of the efficiency and collection properties as a function of the point of incidence, we got evidences of significant alterations of the signals shape in case of particle injection in the inter-strip region. Such an effect, which depends also on the type and energy of the impinging particle, cannot be ascribed only to a mere charge division, especially in case of signals with "wrong" polarity, but to more complex phenomena -for instance charge induction on neighbor strips.In this work we present the results of the qualification campaign carried out exploiting the monochromatic pulsed proton beam facility available at LaBeC of INFN -Sezione di Firenze, focusing the attention on the aforementioned "inter-strip effect". We interpreted the measurements also with the aid of dedicated 3D simulations performed with a custom semianalytical code, which gives a better insight on the physics Manuscript occurring in the device. The impact of the "inter-strip effect" on particle identification scatter plots is also discussed.

In the framework of multi-fragmentation experiments the evolution towards two- (or more) particle correlations with stable and radioactive beams calls for the development of a novel detection system featuring high angular and energy resolution and able to reconstruct the particles momentum at high precision. The proposed detection system, named FARCOS (Femtoscopy ARray for COrrelations and Spectroscopy) will be beneficial for different physical cases. To this aim we are building a prototype detection system featuring four telescopes. Each telescope features an active area of 6.4 cm × 6.4 cm and is composed of three detection stages. The first ΔE stage is a Double Sided Silicon Strip Detector (DSSSD), 300 μm thick, featuring 32 × 32 strips. The second ΔE stage is again a DSSSD, 1500 μm thick, featuring 32 × 32 strips. The third stage, acting as calorimeter, is composed by four CsI(Tl) crystals with an active area of 3.2 cm × 3.2 cm and an absorption length of 6 cm forming a 2 × 2 matrix. The scintillators are readout by a Silicon photodiode 300 μm thick. The paper presents the relevant features of FARCOS and the expected performance of the silicon detection layers, with a special focus on the requirements of the frontend electronics for the DSSSD and the qualification of the DSSSD. In addition we report the first results of the preliminary on-beam tests. © 2012 IEEE
