Abstract :
A very compact solar neutron detector is made by using scintillation fiber and multi-anode photomultipliers. Signals from the 512 channels of the photomultipliers are read-out by CMOS circuitry which has been developed for a KEK B-factory experiment. The circuitry consumes only 5 W of power. The energy resolution for protons is obtained by exposing the detector to the RIKEN accelerator beam and it turns out to be 4.1% for protons at 95 MeV. The sensor will be used for observations on solar neutrons to elucidate the ion acceleration mechanism at the solar surface and also to provide information on-line to the cosmonauts about the impending arrival of strong radiations from the Sun.
