Research Abstract

We use neutrons to study the acceleration mechanism of high energy ions at the solar surface because they are not affected by the interplanetary magnetic field. These neutrons are produced by the interaction between accelerated ions and the solar atmosphere. During this grant, we succeded in operating the very sensitive tracking detector which had been used at the accelerator experiment in USA, on Sierra Negra, 4,600m above sea level, in Mexico. The volume of the detector is 3mx3mx1.7m and much more sensitive than the current solar neutron detectors. Moreover we can get the information on the energy of incident neutrons as well as identifying incident particles. The information on the energy of neutron is essential to understand how efficient particles are accelerated at the solar surface, which has not been understood so far. This new detector is also available for monitoring the intensity of galactic cosmic rays.
