By suppressing the background noise signals through the use of desensitized development conditions, i.e., a developer solution with a pH of 7.3 and a development time of 25 min, for the first time, we have succeeded in identifying the signals from multi-MeV laser-accelerated protons in nuclear emulsions. In addition, the results of a benchmark experiment with 100-MeV protons from a conventional accelerator apparatus confirm that nuclear emulsions have the potential to measure 100-MeV-class laser-accelerated protons., 光・量子ビーム科学合同シンポジウム2019}, title = {Application of nuclear emulsions to laser-driven ion acceleration experiments using micron-sized hydrogen clusters}, year = {2019} }
