Abstract
Equipment for achieving uniformalization of energy and pulsing of a particle beam is installed in an accelerated charged particle-beam generator or particle-beam storage ring. For maximum efficiency, a CMC (cyclotron maser cooling) unit for achieving uniformalization of energy and pulsing of the particle beam is introduced to generate a coherent particle beam.
Claims5
A method of generating a coherent particle beam comprising the steps of:
- generating a particle beam;
- passing the particle beam through a solenoid magnetic field having a magnetic axis parallel to the particle beam;
- producing gyration of the particle beam within the solenoid magnetic field;
- and
- subjecting the gyrating particle beam in the solenoid magnetic field to an electric field having a frequency equal to a frequency of gyration of the particle beam within the solenoid magnetic field along the magnetic axis and having an amplitude so as to bunch particles in the particle beam and produce time coherence of the particle beam.

An apparatus for generating a coherent particle beam comprising:
- means for generating a particle beam;
- a magnetic solenoid for generating a solenoid magnetic field having a magnetic axis extending parallel to and along the particle beam;
- a beam deflector for deflecting the particle beam at the at an entrance of the magnetic solenoid to produce gyration of the particle beam within the solenoid magnetic field;
- a resonant cavity within the magnetic solenoid along the path of the gyrating particle beam;
- and
- means for producing in the resonant cavity an electric field having a frequency equal to a frequency of gyration of the particle beam within resonant cavity along the magnetic axis and having an amplitude so as to bunch particles in the particle beam and produce time coherence of the particle beam.
