Experiment details
Abstract
The E818 experiment is the second INDRA-FAZIA campaign at GANIL, but this time with a complete new electronics and power supply for INDRA after 2 years of work, receiving money from Region Normandie to change the 30 years old electronicsand cables. The goal of the proposed experiment is to confirm the in-medium measurement from an analysis of the intermediate energy heavy-ion collisions leading to vaporization and vaporization-like of the quasi-projectile (QP) and to extend the measure to heavier clusters. The data will be revealed by the FAZIA and INDRA multi-detectors. Two different reactions are considered in order to study two QP sizes. We aim here to measure vaporization-like events from 58Ni+58Ni and 36Ar+58Ni collisions at 74 MeV/nucleon with the INDRA-FAZIA coupled multidetectors, in the D5 room at Ganil. This justifies the use of FAZIA in 'wall' configuration at forward angles, covering a polar angle in the laboratory between 1.7 and 13.6 degrees, in conjunction with INDRA, covering the complementary polar angular range between 14 and 176 degrees. The performance of FAZIA at forward angles will then allow to carry out the isotopic identification necessary for the study on in medium effects for the heaviest fragments, INDRA making it possible to measure in charge all the particles andfragments and in mass the light particles. On the other hand, the better granularity of FAZIA at forward angles (192 telescopes) compared to that of INDRA at thesame angles (96 telescopes) increases the angular resolution by a factor of 2 and will improve the measurement of inter-particle correlations in order to check density. Also, it is important to determine as unambiguously as possible the temperatures reached in these dissipative events; the coincidental measurement of several thermometers, such as kinetic, excited states and isotopic temperatures will provide a significant improvement as compared to previous analyses. It should be noted, however, that this will beat the expense of a lower geometrical acceptance, of the order of 70% for FAZIA compared to 90% in the case of INDRA. The choice of the beam energy is a good compromise between the maximum energy available at GANIL and the lower capability of the FAZIA telescopes to stop high energetic particles as compared to INDRA telescopes.
