Abstract

We report a compact diffusion cloud chamber cooled by thermoelectric (Peltier) modules. After validating particle visualization with a dry-ice chamber, we engineered a reusable TEC system that sustains a supersaturated isopropyl-alcohol layer. Several modules (TEC1-12706, TEC1-12715, TEC2-19006, TEC2-19008) were benchmarked using dimensionless charts. With strong heat-sinking and insulation, a double TEC2-19006 reached −26 °C within ~30 min, while TEC2-19008 reached −33 °C within ~10 min, enabling stable visualization of alpha and background muon/beta tracks. We detail chamber physics, a thermoelectric thermal model, module selection from Qc/Qmax–I/Imax charts, and optical design. The approach offers a robust, low-maintenance alternative to dry ice for extended demonstrations and teaching labs. Quantitative performance metrics, including thermal stability and power consumption analysis, are presented to validate the system's robustness.
