Abstract
A new front-end based on digital GET electronics has been adopted for the readout of the CsI(Tl) detectors of the CHIMERA 4π multi-detector and for the new modular Femtoscopy Array for Correlation and Spectroscopy (FARCOS). It is expected that the coupling of CHIMERA with the FARCOS array, featuring high angular and energy resolution, and the adoption of the new digital electronics will be well suited for improving specific future data analysis, with the full shape storage of the signals, in the field of heavy ion reactions with stable and exotic beams around the Fermi energies domain. Integration of the GET electronics with CHIMERA and FARCOS devices and with the local analog data acquisition will be briefly discussed. We present some results from previous experimental tests and from the first in-beam experiment (Hoyle-Gamma) with the coupled GET+CHIMERA data acquisition.
Highlights
The CHIMERA 4π detector, originally conceived for multi-fragmentation and reaction dynamics studies in the Fermi energy domain [1, 2], has passed different upgrades, in agreement with new experimental and physical needs
Qualification of the GET electronics with CHIMERA detectors The GET electronics, based on the integrated circuit AGET chip, originally designed for Time Projection Chambers (TPCs) and active targets devices has been adapted for CsI(Tl) scintillators and Silicon strip detectors of CHIMERA and FARCOS arrays
Following the building of a first FARCOS module demonstrator and the approval for the construction of 5 FARCOS modules (20 telescopes) we have adopted a compact electronic front end based on the design of new ASIC preamplifiers for silicon strips and FARCOS CsI(Tl) and the GET electronics for digitalization and data readout
