ABSTRACT

This hodoscope is a position sensitive detector used in physics experiments at accelerators,for determination of position resolution of particles generated in nuclear interactions at high energy (√SNN=3-11GeV). This detector is a new type of device which uses plastic scintillators strips coupled to Hamamatsu PIN photodiodes. Usually in this kind of experiments are used position-sensitive devices on base of silicon strips and/or plastic scintillators coupled to photomultipliers(PMT). The first is very good but raises problems in construction, and the second operates at high voltage, resolution is high and its characteristics are affected by magnetic fields. The biggest advantage of the proposed hodoscope consists in easy construction, his characteristics is not influenced by high magnetic fields and has good performance in position resolution (< 5mm). This performance is obtained using an associated electronics which assures a multiparametric determination. The detector structure is made from two perpendicular planes of plastic scintillator strips, each having eight elements. Every strip is coupled to very small charge sensitive preamplifiers.
