摘要:

2015年4月,J-PARC E56(JSNS 2:J-PARC Sterile Neutrino Search using neutrinos from J-PARC Sputron Neutron Source)实验正式获得J-PARC的第一阶段批准。此后,我们开始进行液体闪烁体的研发,以提高能量分辨率和快中子抑制率。此外,我们正在研究雪崩光电二极管(SiPM)内的液体闪烁体。除了研发工作外,还计划使用小液体闪烁体体积进行质子束聚束定时的背景测量,并进行了测量的安全性讨论。本报告描述了研发工作的状态和背景测量,以及第二阶段批准前所需的里程碑。

英文摘要:

On April 2015, the J-PARC E56 (JSNS2: J-PARC Sterile Neutrino Search using neutrinos from J-PARC Spallation Neutron Source) experiment officially obtained stage-1 approval from J-PARC. We have since started to perform liquid scintillator R&D for improving energy resolution and fast neutron rejection. Also, we are studying Avalanche Photo-Diodes (SiPM) inside the liquid scintillator. In addition to the R&D work, a background measurement for the proton beam bunch timing using a small liquid scintillator volume was planned, and the safety discussions for the measurement have been done. This report describes the status of the R&D work and the background measurements, in addition to the milestones required before stage-2 approval.
