Abstract

A novel method for generating GigaGauss solenoidal field in laser-plasma bubble, using screw-shaped laser pulses, is presented. Results of 3D simulations and dependence on parameters of the laser pulse and plasma are discussed. Such fields enable fast synchrotron radiation damping of the beam emittance of laser-plasma accelerated leptons, opening a novel approach for design of laser-plasma FELs or colliders, where beam acceleration stages are interleaved with laser-plasma beam cooling stages.

Summary

GigaGauss and beyond solenoidal fields can be generated in the laser-plasma bubble, using screw-shaped high intensity laser pulses. Beside the standard wake-field and plasma bubble generation, such a laser pulse induces the rotational motion of electrons at the edge of the evacuated plasma region thus creating the solenoidal magnetic field. In comparison with already known techniques which typically rely on interaction with over-dense or solid targets and were producing radial magnetic field localized at the stationary target, our suggested method allows to produce a gigantic solenoidal field, which is co-moving with the driving laser pulse. The solenoid field, semi-stationary in the reference frame of the laser pulse, can be used, in particular, for guiding and providing synchrotron radiation beam emittance cooling for laser-plasma accelerated electron and positron beams, opening up novel opportunities for designs of the light sources, FELs, and high energy colliders. We will discuss the method itself as well as the possible new approach for FEL and collider design, discussing possible layouts and range of parameters of possible FEL and collider facilities. The work builds-up on and expands beyond our report presented in arXiv:1604.01259 [physics.plasm-ph].
