This album show the compact nature of the special cryostat containing the superconducting magnet for the emulsion experiment of the Strasbourg group, as mounted in the neutron room of the synchro-cyclotron at CERN. The incident pion beam comes through the quadrupole focusing magnet at the right (picture 86), is collimated by the pile of lead bricks and is detected by the small plastic scintillation counter immediately to their left. In the left foreground (picture 86) is the liquid-helium container for continuous replenishment of the liquid in the cryostat.
