Laboratorio Testa Grigia
Plateau Rosa (∼3500 m a.s.l.)

• 1979 – 1989 Gamma-ray astronomy with an
array of liquid scintillators
• Cygnus region observations. First detection
of the excess from the source
• Test of the idea of Prof. Chudakov of
studying the cosmic ray spectrum detecting
the Cherenkov light reflected from the snow
• During these years he stayed in Baksan and
worked at Chacaltaya
