Construction and preliminary observation of high sensitive solar neutron detection system

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.
