“…Solar neutrons were first observed in 1982,, 4) but there have only been about a few tens of successful detections so far. Neutrons are not affected by the magnetic field on the solar surface and in the interstellar medium unlike protons and electrons, and thus they reach the Earth with original information about acceleration on the solar surface maintained.…”

The ChubuSat is a Japanese microsatellite technology demonstration mission jointly depeloped by Nagoya university, Daido university, and medium or small-sized aerospace industrial companies in the Chubu area of central Japan. ChubuSat-2 is the second ChubuSat following ChubuSat-1 which was launched by the Russian DNEPR rocket on November 6, 2014. It was selected as one of the four piggyback payloads of the X-ray astronomy satellite ASTRO-H in 2014 summer, and will be launched by the H-IIA rocket from Japan Aerospace Exploration Agency (JAXA) Tanegashima Space Center (TNSC) in winter season of fiscal year (FY) 2015. The ChubuSat-2 mission is devoted to monitoring neutrons and gamma-rays in the ASTRO-H orbit which can be noise sources for ASTRO-H X-ray and soft gamma-ray observations. The mission involves solar neutron observations which were originally proposed by graduate students who joined the leadership development program for space exploration and research, a program for leading graduate schools at Nagoya University. In this paper, we describe the outline of the ChubuSat-2 satellite and the details of the mission instrument, the radiation detector (RD).

“…Therefore, a substantial fraction of high energy solar neutron can reach the vicinity of the Earth. Solar neutrons were detected for the first time dur ing the solar flare on June 21, 1980 using the GRS instrument installed on the NASA research satellite Solar Maximum Mission (SMM) [12]. Later on, solar neutrons were recorded by the same instrument on the SMM [13], by the SONG instrument on the Coronas F spacecraft [14], and in joint measurements of ground based neutron monitors and instruments of the Inte gral space observatory [15].…”

Abstract-The aims and tasks of the space experiment "BTN Neutron" onboard the Russian segment of the International Space Station are described. The experiment deals with detection of fast and epithermal neu trons, X rays, and gamma rays. Characteristics and a short description of scientific instrumentation BTN M1 for this experiment are presented, as well as the first results of operation of the apparatus onboard the station during the first two years of flight.

“…The neutrons can escape from the Sun and be detected at Earth before they decay (e.g. Chupp et a/., 1982), decay at the Sun, or be captured on H or 3 He; capture on H in a quiet photosphere produces 2 H with emission of a 2.223-MeV r-ray having a width expected to be . :S 1 eV, while capture on 3 He produces no r radiation (Hua and Lingenfelter, 1987).…”
