Y. Muraki et al., NEW SOLAR NEUTRON DETECTOR AND LARGE SOLAR-FLARE EVENTS OF JUNE 4TH AND 6TH, 1991, Journal of Geomagnetism and Geoelectricity, 47(11), 1995, pp. 1073-1078
A new solar neutron detector has been designed and has been set at Mt.
Norikura Cosmic Ray Observatory since October 1990. The detector has
successfully detected solar neutrons associated with large solar flare
s of June 4th and 6th 1991. Solar neutrons have been observed also by
a traditional neutron monitor and a muon detector. The authors have co
mpared the observed results obtained by the new neutron detector, the
neutron monitor and the muon detector and the response of each detecto
r to solar neutrons has been discussed.
