First cloud chamber image of a cosmic ray
Bildnummer 11518110
| One of the first cloud chamber photographs showing the track of a cosmic ray,photographed by Dmitry Skobeltzyn in his Leningrad laboratory in 1927. Skobeltzyn was studying electrons knocked from atoms by gamma rays. He subjected his cloud chamber to a powerful magnetic field,causing the tracks of electrons to curve tightly,as demonstrated by most of the tracks in the picture. But a few photographs had straight tracks like the one at top centre. These tracks gave values of electron momentum & energy enormously greater than from any known source,& Skobeltzyn concluded they were fast-moving electrons knocked from atoms by cosmic gamma rays traversing his chamber | |
