The HILI - a multidetector system for light ions and heavy ions

A detector system with a large acceptance, high granularity and a logarithmic response, has been built. It is well suited to detect simultaneously, heavy and light fragments from nucleus-nucleus collisions at energies higher than 10 MeV/nucleon. The angular range spanned by this detector system is ± 20° in-plane and ± 16° out-of-plane with the exclusion of a 2.5° cone around the beam axis. Coverage with a large dynamic range is provided with four large gas filled ionization chambers and behind them a 192-element hodoscope made of individual fast + slow plastic scintillation telescopes in a “phoswich” arrangement.
