Abstract
A racetrack synchrotron employs semi-circular 180 degree dipole magnets having coils which are pulsed by capacitor banks for quickly raising the energy of electrons flowing within the synchrotron. The inclusion of an RF cavity or cavities ensures that the energy of electrons follows the synchronous energy as the synchronous energy increases with the magnetic field. Pulsed quadrupole magnets, along the straight sections of the racetrack, ensure transverse confinement of the electrons. An ejection kicker magnetically diverts electrons from the synchrotron for use by an external device.
Claims8
A pulsed synchrotron configured as a closed ring and comprising:
- parallel spaced straight conduits for containing electron flow therein;
- a plurality of arcuate pulsed bending electromagnets positioned between the straight conduits such that the total bending angle of the bending electromagnets is 360 degrees, and containing therein passages communicating with the straight conduits to guide arcuate electron flow through the bending magnets;
- at least one RF cavity interposed along the ring for synchronous acceleration of the electrons flowing within the ring;
- means for introducing low-energy electrons into the ring;
- means for providing DC power across coils of the electromagnets;
- means of subsequently applying a power pulse across the coils of the electromagnets for contributing in quickly raising energy of the electrons as the RF cavity continues to accelerate the electrons to a vicinity of synchronous energy.
A method for increasing energy of electrons comprising the steps of:
- introducing low energy electrons into a closed ring;
- applying radio frequency excitation to the electrons flowing in the ring thereby causing them to exhibit stable oscillations about a synchronous energy;
- applying DC vertical magnetic fields at curved portions of the ring for a first time interval;
- and
- subsequently applying pulsed vertical magnetic fields at the curved portions of the ring for contributing to increasing the synchronous energy of the electrons.
