Measurement by FIB on the ISS: Two Emissions of Solar Neutrons Detected?
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.
