Piston pour BEBC

The BEBC piston structure and position of a person at the axis. Emile Gastaud, a welder from the CERN workshops (photo 180), had worked on the stainless steel structure of a new piston for the 3.7 m European bubble chamber, BEBC, when an observant photographer achieved this ‘beatification’. The piston is scheduled to be installed in the next few months prior to operation of the chamber with beams from the 400 GeV synchrotron.
