Figure 1. An example of a 'jet' of secondary particles seen in nuclear emulsion following a collision involving a cosmic-ray particle of very high energy. In this case, observed by Daniel, Davies, Mulvey and Perkins in 1952, the particle had an estimated energy of 600 GeV. (The three emulsion photographs reproduced in this article are taken, with acknowledgement to Pergamon Press, from 'The Study of Elementary Particles by the Photographic Method' by Powell, Fowler and Perkins.) md5:a7c55179125dcad5f6609c5d1bc3ecfe	373.4 kB	Preview Download
Figure 2. The famous observation of the T meson in nuclear emulsion exposed to cosmic rays. This was the first clear indication of the existence of the many heavy mesons which have now been identified. The experiment used electron sensitive emulsion, which had just been produced, and was carried out by Brown, Camerini, Fowler, Muirhead, Powell and Ritson in 1948. The T enters the emulsion from the top of the photograph; b and c are JI+ mesons; a is a J t - meson which gives rise to a star at B. md5:07772973e26b6cf6aa8ddfcf40303975	237.4 kB	Preview Download
Figure 3. The first observation of a 'hyperfragment'. The nuclear fragment, f, disintegrated at B, and measurements on the tracks 1, 2 and 3 indicated that the A0 hyperon was a component of the nuclear fragment. The observation, using nuclear emulsion, was made by Danysz and Pniewski of the Warsaw Group in 1953. md5:3859c8154501228b72f889389523f0cc	322.5 kB	Preview Download
Figure 4. A schematic diagram of the A0 magnetic moment experiment. The entire region shown here (target to emulsion stack) lies inside the pulsed magnetic field. md5:9a0e218aebbae82a49708c30398ea695	190.2 kB	Preview Download
Figure 5. The A0 magnetic moment experiment. The block in the centre is the pulsed magnet containing the emulsions. The beam comes out of the quadrupole magnet seen at the top right of the photograph. md5:f21f9c1d937eb5c9cc7bb3f68e244be1	311.1 kB	Preview Download
