CERN/ALICE is an experiment at the Large Hadron Collider optimized or the study of heavy-ion collisions at a center-of-mass energy ≈5.5 TeV. The aim of the experiment is to study in detail the behaviour of matter at high densities and temperatures, QGP, in view of proving de-confinement and chiral-symmetry restoration. ALICE/PHOS-China group joins the design, construct, test and setup of PHOS devoted to the study of photon signals. PHOS(photon spectrometer) is an electromagnetic calorimeter consisting of 17 920 detection channels of PbWO4, of 2.2 cm × 2.2 cm × 18 cm dimensions, coupled to large-area PIN diodes with low-noise preamplifiers. The first task is R&D of readout device
