New Milestones in Doubler Progress

The first 22 ft. bending magnet for the Fermilab Energy Doubler passed a performance test on March 12. This is the first magnet produced on the new production line that started January 20th. Magnets for the Doubler will be produced at the rate of one each month, with production increasing as they are installed in the Main Ring.

Location of the Energy Doubler in the Main Ring tunnel has been changed. It will be located below the present Main Ring instead of at the top of the tunnel enclosure. The two beams will now be 18 inches apart vertically, and aligned horizontally. Beam manipulation between the two rings will be easier and colliding the two beams becomes a possibility.
