THE SUPPLY SYSTEM FOR THE MAGNET OF THE PROTON SYNCHROTRON OF THE CERN IN GENEVA
In the 25-Bev proton synchrotron of the CERN in Geneva, the energy required for energizing the magnet is obtained from a mechanical store in the form of rotating masses, to which it is returned when the magnets are de- energized. In accordance with the operating requiremerts, the magnet current must be raised from zero to 6.4 ka in 1.1 sec and reduced-back to zero in 1 sec, during which time the magnet voltage must be kept constant to within plus or minus 0.2%. A total of 24 grid-controlled mutators are employed to control this exchange of energy. The peak power of 38.4 Mw is supplied by a turho-alternator driven by an induction motor. The speed of this motor is governed by an electronically cortrolled Scherbius set. This new system prevents the load surges from having any repercussions on the supply network, end it provides an average output of about 2.6 Mw, for which the motor is dimensione.d The control equipment for the converter supplying the current is designed in such a manner that the load on the network remains uniform and free of surges and the magnet voltage is kept constant during the build-up of the field.
