Abstract :
Studies with different CsI(Tl) crystals coupled to avalanche photodiodes were performed in the frame of the R+D programme for the design of the R3B calorimeter (CALIFA). The study of the energy resolution has been performed for crystals with lengths varying from 1 to 10 cm and square section (1 times 1 cm2), attending to different optimization of parameters (i.e., crystal wrapping, optical coupling to the avalanche photodiode and the electronic chain). The obtained results with avalanche photo-diodes are very promising and suggest CsI(Tl) as a suitable candidate for at least part of the calorimeter.
