Progress in Chromatic Calorimetry Concept: Improved Techniques for Energy Resolution and Particle Discrimination

Abstract: This study introduces chromatic calorimetry, a novel particle detection method that uses strategically layered scintillators with different emission wavelengths. This approach aims to enhance energy measurement by capturing particle interactions at different shower depths through wavelength-based discrimination. Our experimental validation of this novel method utilizes an arrangement of scintillator materials to improve energy resolution and particle identification. The stacking arrangement of scintillators is organized by their emission wavelengths to track the development of electromagnetic and hadronic showers. By testing electrons and pions with energies up to 100 GeV, the setup demonstrated better discrimination and provided detailed measurements of shower profiles. The results indicate that our experimental validation significantly aims to enhance particle identification and energy resolution, highlighting its potential value in high-energy particle detection. Future work will explore the integration of Quantum Dots (QD) technology to advance these capabilities in chromatic calorimetry further.
