The purpose of this project is to investigate the acceleration mechanisms of high energy ions at Solar flares by observing energy distributions and time profiles of neutrons produced in the Solar atmoshpere by the accelerated ions. These neutrons are expected to bring us information concerning the accelerations of ions, since neutrons are not affected by the magnetic field between the Sun and the Earth.During this grant, in order to set a particle tracking detector (SciBar), which had been used at the accelerator experiment, on the top of Sierra Negra (4600 m above sea level) in Mexico as a observational equipment for the above purpose, preliminary observation at the site using a prototype detector had been done. After examinations and designings by comparing the results of the observations with computer simulations, a high sensitivity solar neutron detection system (SciCRT) has been constructed and started.

该项目的目的是通过观察加速离子在太阳amoshpere中产生的中子的能量分布和时间曲线来研究太阳耀斑处高能离子的加速机制。 These neutrons are expected to bring us information concerning the accelerations of ions, since neutrons are not affected by the magnetic field between the Sun and the Earth.During this grant, in order to set a particle tracking detector (SciBar), which had been used at the accelerator experiment, on the top of Sierra Negra (4600 m above sea level) in Mexico as a observational equipment for the above purpose, preliminary observation at the site使用原型检测器已完成。在检查和设计通过将观测结果与计算机模拟进行比较后，已经构建并启动了高灵敏度太阳中子检测系统（SCICRT）。
