Aimant AEG pour spectromètre de masse

The largest and heaviest item sent to Serpukhov in 1969/70 was a spectrometer magnet weighing 110 tons which arrived at CERN in August 1969. This magnet would make it way to Serpukhov by train and ship after being tested at CERN. These tests would include installation in the current experiment at CERN. During the autumn shutdown of the proton synchrotron the magnet, which had a larger aperture (1.5 x 1 m²) and higher field, would replace the one in use at the time. There would then be several weeks of operation using almost all the equipment which was scheduled for the expeiment at Serpukhov.
