Abstract EN
A new type of solar neutron detector (FIB) was launched on board the Space Shuttle Endeavour on July 16, 2009, and began collecting data at the International Space Station (ISS) on August 25, 2009.
This paper summarizes the three years of observations obtained by the solar neutron detector FIB until the end of July 2012.
The solar neutron detector FIB can determine both the energy and arrival direction of neutrons.
We measured the energy spectra of background neutrons over the South Atlantic Anomaly (SAA) region and elsewhere and found the typical trigger rates to be 20 and 0.22 counts/sec, respectively.
It is possible to identify solar neutrons to within a level of 0.028 counts/sec, provided that directional information is applied.
Solar neutrons were possibly observed in association with the M-class solar flares that occurred on March 7 (M3.7) and June 7 (M2.5) of 2011.
This marked the first time that neutrons had been observed in M-class solar flares.
A possible interpretation of the production process is provided.
