A particle identification technique for large acceptance spectrometers

A technique to identify the heavy ions produced in nuclear reactions is presented. It is based on the use of a hybrid detector, which measures the energy loss, the residual energy, the position and angle of the ions at the focal plane of a magnetic spectrometer. The key point is the use of a powerful algorithm for the reconstruction of the ion trajectory, which makes the technique reliable even with large acceptance optical devices. Experimental results with the MAGNEX spectrometer show a remarkable resolution of about 1/160 in the mass parameter.
