Mass Production of Large-sized Nuclear Emulsion Plates for J-PARC E07 Ito, Hiroki Endo, Yoko Hoshino, Kaoru Khin Than Tint Kinbara, Shinji Kobayashi, Hidetaka Mishina, Akihiro Myint Kyaw Soe Xue, Yaling Yoshida, Junya Hai, Zhang Dong Nakazawa, Kazuma In the E07 experiment at J-PARC, we systematically study double strangeness (S = -2) systems on Λ-Λ and Ξ--N interaction via S = -2 nuclei such as double Λ hypernuclei and twin Λ hypernuclei with hybrid-emulsion method. The number of S = -2 nuclei is planned to be about 102 which is 10 times or more events than that of the E373 experiment at KEK-PS. We have to prepare for large-scale emulsion plates by huge amount of emulsion gel with weight of 2.1 t, which is about 3 times’ quantity used for E373. To make it possible, we have developed methods for treatment of supporting films and for making emulsion plates. We have successfully produced 1500 plates. 2015 http://hdl.handle.net/20.500.12678/0000000895 https://meral.edu.mm/records/895
