Decreasing the bandwidth of linear and nonlinear Thomson scattering radiation for electron bunches with a finite energy spread

Blog Article

Relative narrow bandwidth-high energy radiation can be produced through Thomson scattering, where highly relativistic electrons collide with a laser pulse.The bandwidth of such a source is determined, among others factors, by the bandwidth of the laser pulse and the miami dolphins wordmark energy spread of the electrons.Here we investigate how the bandwidth of such a source can be minimized, with a particular emphasis on electron bunches with a correlated energy spread of several percent, that are typical for plasma based accelerator schemes.We show that by introducing a chirp on the laser pulse it is possible to compensate the broadening effect due twist and lick oral gel to the energy spread of the electrons, and obtain the same bandwidth as a quasi-monochromatic plane wave laser pulse colliding with a monoenergetic electron bunch.Ultimately, the bandwidth of a Thomson source is limited by the acceptance angle and the initial transverse momentum of electrons (emittance).
