Figure 13: Energy ratio between converted protons ( ) versus incident neutrons ( ). Proton energy ( ) was measured using the range method by the FIB sensor, while neutron energy was estimated by flight time. We assumed that the solar neutrons departed at the same time (19 : 52 UT) from the Sun. There is an event beyond 1.0. However taking account of the energy resolution of the sensor, it sometimes happens.
