A Detector System for Low-Energy Light Heavy-Ions

A detector system for low-energy light heavy-ions has been designed and tested. It consisted of a time-of-flight spectrometer and a ¿E-E telescope. The amount of material in front of the ¿E and E detectors, i e two time-of-flight detectors and the entrance window for the ¿E ionization chamber, was only about 40 ¿g/cm2. This fact in combination with good energy and time resolution made it possible to achieve complete identification of ions with A ¿ 30 and Z ¿ 15. Of particular interest is that this performance was reached down to low energies, E/A ¿ 0.3 MeV/nucleon.
