The light output of the 324 CsI(Tl) scintillators of INDRA has been measured over a large range both in energy: 1 - 80 AMeV and in atomic number of incident ions: Z = 1 - 60. An analytical expression for the nonlinear total light response as a function of the energy and the identity of the ion is proposed. It depends on four parameters. For three of them, connected to CsI(Tl) intrinsic characteristics, recommended fixed values are proposed. They are issued from the comparative study of the forward scintillators of INDRA, based on intermediate mass fragment data. The fourth one, related to light collection and to the gain of the associated photomultiplier, is particular and may be accurately obtained afterwards, from light charged particle data. Two applications are presented: fragment identification in telescopes using a CsI(Tl) crystal as residual energy detector and the scintillator energy calibration. The results are successfully confronted to heavy fragment experimental data.
This article describes the crystal selection and quality control utilized to develop and calibrate a high resolution array of CsI(TI) scintillator crystals for the detection of energetic charged particles. Alpha sources are used to test the light out
Profiting from previous works done with the emph{INDRA} multidetector on the description of the light response $mathcal L$ of the CsI(emph{Tl}) crystals to different impinging nuclei, we propose an improved $Delta E - mathcal L$ identification-calibr
The inorganic crystal scintillator CsI(Tl) has been used for low energy neutrino and Dark Matter experiments, where the intrinsic radiopurity is an issue of major importance. Low-background data were taken with a CsI(Tl) crystal array at the Kuo-Shen
Semi-empirical method of calculation of quenching factors for scintillators is described. It is based on classical Birks formula with the total stopping powers for electrons and ions which are calculated with the ESTAR and SRIM codes, respectively. M
The equation of state of asymmetric nuclear matter is still controversial, as predictions at subsaturation as well as above normal density widely diverge. We discuss several experimental results measured in heavy-ion collisions with the INDRA array i
