Groundbreaking. An informal ceremony was held October 3 to break ground for the main-ring enclosure. Members of the Main-Ring Section and many others from DUSAF, AEC, and the Laboratory participated. Figure 5 shows the ceremony at the height of the activity

Plans for Magnet Production. The rented factory building in West Chicago mentioned in last month's report will be developed into a magnet-production facility. All the inner coils of the bending magnets will be fabricated and approximately 10% of the bending-magnet cores stacked and assembled here. Most of the bending-magnet cores, all of the bending-magnet outer coils and all of the quadrupole cores and coils will be fabricated by private industry. All assembly of cores, coils, and vacuum chambers into complete bending magnets and quadrupoles will be done on production lines we are now setting up at the West Chicago facility. Mechanical, electrical, and magnetic testing -9NAL-33 0090.01 of the completed magnets will also be done at this facility, which is being equipped to produce magnets at a rate to meet the goal of completing installation of main-ring components by July 1
