Energy Resolution of the Solar Neutron Detector of JEM on ISS

A solar neutron detector will be launched on the 2. NEW SOLAR NEUTRON DETECTOR Japan Exposure Module (JEM) of the International Space Station (ISS) in May 2009. The detector comprises scintillation fiber and is designated as the Space Environment Data Acquisition (SEDA)-FIB. It tracks the recoil protons induced by neutrons and measurement of the proton energy using the range method. The energy resolution of the detector was measured using the proton beam at Riken. Herein, we report the FIB detector energy resolution. (authors)
