[O11-P72] Comparison of cosmic rays detection efficiency by reflective materials using Cosimc Watch

*Meika Toda1 (1.Accel Kitchen)

Focusing on the role of refrective materials in Cosmic Watch, experiments were conducted to find more suitable reflective materials and to improve detection efficiency. Experiments were conducrued using aluminum foil, crumpled alminum fol, and no reflective material, and detection effciency was evaluated by foucasing on the number of detections and adc value distribution, respectively.
