Resonant Laser Cooling of Circular Accelerator Beams

The resonant laser cooling of circular accelerator beams of relativistic charged particle is studied. It is shown that in the approximation of the given external electromagnetic wave amplitude (small gain free electron laser) the emittance of a beam of charged particles decreases. In the field of particle energy about 100 in the mass energy units the beam energy losses are negligible. The discovered effect can be used for cooling of charged particle beams in various accelerators. The significant cooling rates are possible to achieve by placing of the cooling device in the appropriate points of the accelerator orbit. Resonant laser cooling for various cases are considered. This method of charged particle beams cooling can be applied to circular accelerators of electron and various relativistic heavy particle beams and has significantly, about 3-4 orders of magnitude, shorter cooling time in comparison to any other cooling method.

Effect of Density Correlations on the Coherency of Relativistic Bunch Radiation

The coherent radiation of the electron beam with account of particle position correlations because of strong Coulomb interaction is considered. For the first time it is shown that the coherency of the radiation of the bunch with account of correlations depend on the mean inter particle distance (mean density of the bunch). The conditions of coherency are found. The influence of deviations from mean distance on the radiation coherency is considered.

Resonant Laser Cooling of Relativistic Charges Beams

In work is considered average transverse dynamics of an electron beam in the autoresonant laser. It is shown, that in approach of the given external electromagnetic wave (small gain free electron laser) transverse emittance of a beam of the charged particles decreases. This for the first time found out effect can be used for cooling beams of various accelerators of the charged particles. In the field of particle energy about 100 in the mass energy units, beam energy losses are negligible. This method of charge beams cooling may be applied to electron, muon and various heavy particle beams.

Coherent Radiation of Crystalline Beams

Crystallization and radiation of accelerator beams is considered. For the first time it is shown that crystallization conditions for charged particle beams differs from those of plasma. Crystallization conditions of charged relativistic bunches are found and shown that they may be satisfies in existing linacs. The coherence radiation of crystalline beams in the XUV region is investigated. Necessary conditions of coherency are found. The influence of deviations from mean interparticle distance on the radiation coherency is considered.
