“…As neutrons don't possess any electric charge their trajectories in space aren't influenced by magnetic fields. They travel from the area of generation to the place of registration in the vicinity of Earth along a straight lines, unlike of charged particles which have curved trajectory, "wrapping" over power lines of the Sun magnetic field, passing longer way in comparisons with neutron one [2]. Observations of solar neutrons can be implemented by means of the ground facilities conducting continuous monitoring of space radiation.…”

Abstract. This research is devoted to solar neutron search in the flux of the particles emitted by the Sun during solar flare by means of the neutron detector of the magnetic spectrometer PAMELA. The main objectives of our research were to study the background conditions in the Resurs-DK1 satellite orbit during the periods of quiet Sun and to develop the methods of solar neutron search in the flux of high-energy solar particles. The tasks of study were as the analysis of the neutron detector count rate during solar flares with possible generation of neutrons and the attempt to detect the stationary neutron flux from the Sun in weak flares. The analysis was carried out for 28 solar events when neutrons could be produced during the period from December 2006 till October 2015.

“…Identifying and characterizing solar neutrons are important goals of solar physics. As uncharged particles, they are unaffected by solar magnetic fields and can therefore provide key insight regarding solar acceleration processes [Hua et al, 2002;Dorman, 2010;Vilmer et al, 2011;Feldman et al, 2010;Lawrence et al, 2014a]. Prior studies have reported the detection of solar neutrons using MESSENGER NS data for specific times associated with enhanced solar activity [Feldman et al, 2010;Lawrence et al, 2014a], although the specific solar nature for one of these events has been disputed [Share et al, 2011].…”

Neutrons and energetic charged particles in the inner heliosphere: Measurements of the MESSENGER Neutron Spectrometer from 0.3 to 0.85 AU

et al. 2015

Energetic charged particle and neutron data from the Neutron Spectrometer (NS) on board the MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) spacecraft have been acquired for solar distances ranging from 0.3 to 0.85 AU. The NS is sensitive to ions with energies greater than 120 MeV/nucleon and has made the first measurements of these energetic ions in the inner heliosphere since the mid-1970s. The high-energy ion measurements are well correlated with Earth-based neutron monitor measurements, which themselves provide a measure of the solar modulation of galactic cosmic rays (GCRs). These measurements provide an explicit demonstration of the expected GCR solar modulation for solar distances to 0.3 AU. These NS data also represent the first interplanetary neutron measurements in the inner heliosphere. The time variability of the neutron measurements are driven by two primary effects: time variable production of neutrons from GCRs interacting with local spacecraft material and small count rate changes due to temperature-driven gain changes in the NS instrument. When these time-dependent variations are removed from the neutron measurements, there is no statistically significant variation of neutron count rates versus solar distance. These data are used to derive an upper limit on solar neutron production of 10 24 neutrons [0.5 < E < 9 MeV] sr À1 s À1 during quiescent periods.
