Abstract :
The HERACLES-II multidetector is an array composed of several types of detectors and is used to study heavy ion reactions at intermediate energies. The original version was designed to detect fragments produced by collisions between 20 and 100 A MeV. In order to use the radioactive beams accelerated by ISAC-II ( E proj ≤ 15 A MeV ) , the matrix was moved to TRIUMF and underwent an overhaul. The detector thresholds were lowered and the first rings (low angle) were replaced. Tests at 9.2 A MeV allowed us to evaluate the efficiency of the new setup at low beam energy.
