We are using nuclear emulsion for cosmic ray radiography. It has 180 micrometer polystyrene base and 70 micrometer emulsion layer on both side. We want to choose high energy muon for higher resolution imaging. We develop thick base type nuclear emulsion for improvement of angular accuracy to measure smaller scatter angle and evaluate higher momentum.
