Prototype Test for Electromagnetic Calorimeter, FOCAL, at CERN-SPS Using Large Dynamic Range Readout Electronics

A silicon–tungsten prototype calorimeter, for the proposed ALICE LS3-upgarde, was fabricated and tested at CERN-SPS beamline facility in year 2017. The calorimeter designed with help of GEANT4 simulation to perform a high multiplicity density environment optimised energy position resolutions incident up 200 GeV. There were several tests conducted different configurations both laboratory CERN facilities. latest series consists 20 layers, each layer consisting 6 * array 1cm2 silicon pad detector, on single 300 um thin wafer, 1 radiation length (XR) thick, 10 cm pure tungsten plates as absorbers. Data collected pion, muon, electron over wide range energies (20–180 GeV). Because large deposition within by electromagnetic showers, readout electronics need have dynamic range. Here, we will discuss performances prototype, experimented CERN-SPS, using newly developed (ANUINDRA) (up 2.6 pC) compare improvements this regard.
