我们在实验快堆JOYO上用0.76吨钆液体闪烁探测器进行了中微子探测研究。该探测器安装在距JOYO 140 MW火电机组堆芯24.3m的地面上。反应堆开关比较测得的中微子事件率为1.11±1.24（统计数据）±0.46（系统）事件/天。虽然测量的统计意义是不够的，在这样一个紧凑的探测器在地面上的背景进行了详细的研究和MC模拟被发现描述的数据。还示出了用于未来此类实验的检测器的改进的研究。
We carried out a study of neutrino detection at the experimental fast reactor JOYO using a 0.76tons gadolinium loaded liquid scintillator detector. The detector was set up on the ground level at 24.3m from the JOYO reactor core of 140MW thermal power. The measured neutrino event rate from reactor on–off comparison was 1.11±1.24(stat.)±0.46(syst.)events/day. Although the statistical significance of the measurement was not enough, backgrounds in such a compact detector at the ground level were studied in detail and MC simulations were found to describe the data well. A study for improvement of the detector for future such experiments is also shown.
