摘要
To investigate complex fragment emission in intermediate energy nucleus-nucleus collisions, an array of three-element telescopes has been constructed. The array is designed to measure energy, charge and emission angles of fragments with Z values from 2 up to the projectile atomic number when studying reactions in reverse kinematics. In this case it has a good efficiency even for events with complex fragment high multiplicity. Each telescope is made of an ionization chamber (filled with CF4 at a pressure up to 300 mbar), a Si detector (500 mum thick, position sensitive in two dimensions) and a CsI(Tl) scintillator with photodiode readout.
