The aim of this project is to design, manufacture and operate a calorimeter that, in high-radiation environments, generates a signal by producing and multiplying secondary emission electrons from sampling layers in order to measure the energies of particles (such as electrons, photons, neutrons and protons). Calorimeters used in particle physics and nuclear physics rely on determining the properties of particles by fully absorbing them within the material employed. The calorimetry method, which is particularly widespread in particle physics, measures the energy of high-energy particles by allowing the electromagnetic and hadronic showers they create when interacting with an absorber made of high-Z elements to interact with other, light-emitting materials (scintillation or Cherenkov), known as the active components. In this type of calorimeter, the greatest problem encountered in high-energy experiments is that the active components lose their signal-generating efficiency over time because of radiation, and that these radiation effects cannot be entirely eliminated by the calibration methods required for precise measurements.
