Research Abstract
A new nuclear emulsion production facility has been established which has 10 times production power than running machine at the time of this plan. We supplied nuclear emulsion films for the DsTau, FASER, SND@LHC, NINJA, and GRAINE experiments, a total nuclear emulsion surface of 380 square meters in 2022, and 1,060 square meters in 2023, exceeding the planned target of 1,000 square meters per year. In order to read tracks from nuclear emulsion films faster, two methods were developed to improve the contrast of the tracks after development for the scanning system (HTS2) with reduced magnification. The first was achieved by developing a nuclear emulsion with enlarge the size of silver bromide crystals by adjusting parameters such as chemicals and temperature during nuclear emulsion manufacturing. The second uses normal nuclear emulsion films, but a development method that changes the developing agent but enlarge the size of chemical developed silver grains(Solution Physical Development).
