Chaotic electron dynamics for relativistic-electron-beam propagation through a planar wiggler magnetic field.

It is shown that the motion of an individual test electron in a low-density relativistic electron beam propagating through a realizable planar-wiggler magnetic field is nonintegrable and can become chaotic. The chaoticity, which is induced by the transverse spatial inhomogeneities in the wiggler field, poses limits on the wiggler field amplitude and the beam size for beam propagation and free e...

Self-Fields Effects on Gain in a Helical Wiggler Free Electron Laser with Ion-Channel Guiding and Axial Magnetic Field

In this paper, we have investigated the effects of self-fields on gain in a helical wiggler free electron laser with axial magnetic field and ion-channel guiding. The self-electric and self-magnetic fields of a relativistic electron beam passing through a helical wiggler are analyzed. The electron trajectories and the small signal gain are derived. Numerical investigation is shown that for grou...

Experimental Study of Self Modulation Instability of ATF Electron Beam

In this paper, We investigate numerically the development of self-modulation instability (SMI) with electron bunch parameter available at Accelerator Test Facility (ATF) of Brookhaven National Laboratory (BNL). The results show that the long bunch drives wakefields with periods one to one fifth of the bunch length in plasmas with various densities. Both 50 pC and 1 nC electron bunches are inves...

Plasma Wave Acceleration of Electron in Bubble Regime in Presence of a Planar Wiggler

The plasma wave acceleration of electron in the bubble regime is investigated in a new configuration containing a planar wiggler. The space-charge field of the laser-created ion channel can focuse and stabilize the electron trajectory to guide it toward the acceleration region. The high-gradient plasma wave field can resonantly accelerate the trapped electron to higher energies in the presence ...

Electron Beam Dose Distribution in the Presence of Non-Uniform Magnetic Field

Introduction Magnetic fields are capable of altering the trajectory of electron beams andcan be used in radiation therapy.Theaim of this study was to produce regions with dose enhancement and reduction in the medium. Materials and Methods The NdFeB permanent magnets were arranged on the electron applicator in several configurations. Then, after the passage of the electron beams (9 and 15 MeV Va...
