首次研制了一套自动跟踪系统，用于跟踪束流达到极限的核乳胶片上的径迹。在新技术的辅助下，系统的跟踪率达到99.5%。通过一张厚厚的乳胶片，轨道的工作速度不到1分钟，而比有人的半自动系统快15倍。该系统工作24小时，用于J-PARC的E07实验，使在一年内探测到具有双重奇异性的~102个核(S=−2核)成为可能。在分析鉴定S=−2核的核物种时，该系统在跟踪S=−2核向球面方向发射的径迹、测量跟踪迹的长度等重要步骤中表现出相当不错的工作。
An automatic track following system has been successfully developed to follow tracks in nuclear emulsion sheets exposed with beam up to the limit to be observed for the first time. The track followed rate of the system is 99.5% with the assistance of the new techniques. The working speed for a track is less than 1 min through one thick emulsion sheet, whereas it is 15 times faster than that of semiautomatic system with human. The system working for 24 h is applied for the E07 experiment at J-PARC and makes it possible to detect ~102nuclei with double strangeness (S=−2 nuclei) within one year. Regarding analyses to identify nuclear species of S=−2 nuclei, the system shows quite decent job for significant steps such as following tracks emitted to spherical directions from S=−2 nuclei, measurement of lengths of followed tracks, and so on.
