“…The reaction 93 Nb + nat Mg was measured during a campaign of experiments for which INDRA was coupled to the CHIMERA ( [25] - [27]) first ring, which covered the angular range from 1 • to 3 • , and some INDRA modules in the horizontal plane were replaced by silicon strip detectors. However, for the present reaction study, none of these additional detectors were used.…”

We analyzed the 93 N b on nat M g reaction at 30 MeV/nucleon in the aim of disentangling binary sequential decay and multifragmentation decay close to the energy threshold, i.e. ≃ 3 MeV/nucleon. Using the backtracing technique applied to the statistical models GEMINI and SMM we reconstruct simulated charge, mass and excitation energy distributions and compare them to the experimental ones. We show that data are better described by SMM than by GEMINI in agreement with the fact that multifragmentation is responsible for fragment production at excitation energies around 3 MeV/nucleon.

“…In order both to improve the LCP-Id and to simplify the electronic chain of multidetector telescopes, we have carried out some tests using commercial sampling analog-to-digital converter modules to perform real-time digital pulse-shape analysis of the signals coming from a standard detection cell of a CHIMERA (Charged Heavy Ion Mass and Energy Resolving Array) multidetector [1], [2], (i.e., a telescope of a 300 m silicon detector and a cm CsI(Tl) scintillator coupled to a photodiode). First, we have performed the on-beam and on-line LCP-Id for the CsI(Tl), by using only the standard electronic chain for measuring slow components with CHIMERA, with the charge-todigital converter (QDC) replaced by the sampling analog-todigital converter.…”

A 100 Msamples/s 14-bit sampling analog-to-digital converter has been used to perform digital pulse-shape acquisition of signals collected from CHIMERA telescopes. Two different kinds of tests have been carried out to check the performances. The signals from a typical CHIMERA detection cell have been collected using both a standard CHIMERA electronic chain up to the amplifier, and a very simple analog front end, basically reduced to the preamplifier. The obtained on-beam and on-line results are presented.Index Terms-Digital pulse shape acquisition, digital signal processing, multidetector arrays, particle identification, simple analog front end.

The problem considered in this work is the classification of the particles produced by the collision of a heavy ion beam on a target. Each particle is captured by a detector and results in a signal (which is the impulse response of a dynamic linear system), which is measured by a digital acquisition system. The assumption made herein is that the shape of the impulse-response contains complete information on the particle, and the classification can be done by pulse-shape, analysis.In this work, a complete procedure for the particle identification is proposed. The main idea is to use the cascade of a state-space identification algorithm and a parametric non-linear map using the model parameters as input regressors. The algorithm has been tested on a large set of impulse-responses and provides a fully automatic accurate classification of the isotopes.This work focuses on isotopic identification of the most energetic light charged particles (LCP). All the experiments are made with the large detector array CHIMERA (Charge Heavy Ions Mass and Energy Resolving Array).
