Abstract
THE SOLAR NEUTRINO PROBLEM IS ONE OF THE LONGEST- STANDING UNRESOLVED PROBLEMS IN THE UNDERSTANDING OF THE ENERGY-PRODUCING PROCESSES IN THE SUN. THE OBSERVED FLUX OF NEUTRINOS IS ABOUT ONE-FOURTH OF THAT PREDICTED BY CAREFUL CALCULATIONS OF SOLAR-FUSION REACTIONS. THE POSSIBILITY OS RESOLVING THIS ISSUE WILL BE STUDIED BY THE USE OF NOVEL NEUTRINO DETECTOR USING INDIUM PHOSPHIDE DETECTORS. IN PHASE I A SERIES OF EXPERIMENTS ON INP CRYSTALS AND A DETAILED STUDY OF THE DESIGN OF THE EVENTUAL DETECTOR WILL BE CARRIED OUT TO EVALUATE THE POTENTIAL SUCCESS OF THIS SCHEME. INP IS A III-V SEMICONDUCTOR THAT HAS RECENTLY FOUND EXTENSIVE USES IN ELECTROLUMINESCENT DEVICES AND, AS A RESULT, IS COMMERCIALLY AVAILABLE. THE EVENTUAL DETECTOR WOULD BE ABOUT ONE CUBIC METER IN SIZE, MUCH SMALLER THAN ANY PREVIOUS NEUTRINO DETECTOR, AND WOULD HAVE THE SIGNIFICANT ADVANTAGES OF A LOWER NEUTRINO ENERGY THRESHOLD COMBINED WITH A SPECTROSCOPIC CAPABILITY.
