Cosmic-ray intensity at great depths and neutrino experiments

  • Published:
Il Nuovo Cimento (1955-1965)

Summary

A group from the Tata Institute of Fundamental Research, Bombay, has recently completed measurements on cosmic-ray intensities deep underground up to depths of 8400 m w.e. On the basis of these observations it is suggested that, for investigations on naturally occuring neutrinos, there are great advantages to be gained by performing the experiments at considerable depths — around 9000 ft. — below the earth‘s surface, essentially because of the very low background which is encountered at such depths. Some features relevant to neutrino physics which emerge from the measurements already made and the design of future experiments to detect cosmic ray produced and extra terrestrial neutrinos are discussed.

Riassunto

Un gruppo del Tata Institute of Fundamental Research, Bombay, ha recentemente completato le misure delle intensità dei raggi cosmici sotterra sino a profondità di 8400 m a.e. Sulla base di queste osservazioni si suggerisce che si potrebbero ottenere grandi vantaggi eseguendo esperimenti a considerevoliprofondità — circa 9000 ft. — sotto la superficie, essenzialmente grazie al bassissimo fondo che si riscontra a queste profondità. Si discutono alcune caratteristiche, interessanti per la fisica del neutrino, che emergono dalle misure già fatte ed il progetto di nuovi esperimenti per rivelare i raggi cosmici prodotti ed i neutrini extra terrestri.
