Cosmic ray imaging is a non-destructive visualization technique that uses cosmic rays to inspect the internal structures of objects. We employ nuclear emulsions, a type of solid-state track detector, for cosmic ray observation. In previous studies, we aimed to improve detector sensitivity by increasing the size of silver bromide crystals, which serve as the photosensitive material, and by optimizing the chemical sensitization conditions accordingly. In addition to the effects of crystal enlargement, this study hypothesized that crystal shape also influences the chemical sensitization process. Therefore, we evaluated the relationship between crystal shape and detector sensitivity.
