nuclear emulsion

Cosmic ray imaging is a technique for non-destructively visualizing the interior of large-scale structures using cosmic ray muons. We have used nuclear emulsion plates as cosmic ray detectors. Nuclear emulsion plates are made by coating a support with an emulsion consisting of gelatin and silver bromide crystals. In previous studies, we succeeded in improving the sensitivity of nuclear emulsion plates by increasing the silver bromide crystal diameter from approximately 200 nm to approximately 300 nm. In this study, we chemically sensitized 300 nm nuclear emulsion plates under several different conditions and compared their performance.
