CERN History: Giant magnets come to CERN in the 1950s

In CERN's 60th year, we look back at some of its historic moments. Here magnet coils for the Synchrocyclotron make their journey to Geneva in 1955

In the year when CERN turns 60, it is fitting to look back at some of the key historic moments. In the video above, from 1955, a magnet coil for the Synchrocyclotron (SC) makes an epic journey to Geneva, Switzerland. Two coils were needed for the SC, each weighing 60 tonnes and measuring 7.2 metres in diameter. They were manufactured in Belgium before travelling to Basel in Switzerland by boat and continuing by road to Geneva. The first coil reached Geneva in December 1955, with the second following in early 1956.

A special trailer with a hydraulic mechanism tilted the coil whenever the road became too narrow, such as through the village streets of Coppet and Morat, as seen in the video above. Such a spectacular sight had never before been seen in the region, and it was the first in a long series of epic transport operations that have marked the history of CERN.

The Synchrocyclotron, CERN’s first accelerator, was up and running by 1957 and operated until 1990. Recently refurbished, and previewed at the CERN open days last year, the synchrocyclotron will soon become a permanent exhibit at CERN.
