Abstract: Harmonic lasing of low-gain free electron laser oscillator has been experimentally demonstrated in terahertz and infrared region. Recently, together with the high-reflectivity high-resolutio...
Radiative instability of a relativistic electron beam moving in a photonic crystal
Radiative relativistic electron beam photonic crystal
2010/11/16
The radiative instability of a beam moving in a photonic crystal of finite dimensions is studied. The dispersion equation is obtained. The law $\Gamma\sim \rho ^{1/\left( {s + 3} \right)}$ is shown to...
Return-current formation in the electron beam–plasma system
Return-current formation electron beam–plasma system
2009/10/30
Using a 3-D electromagnetic particle-in-cell model an evolution of the electron distribution function in the beam-plasma system with the return current is computed. It was found that the resulting ele...
Axial electric wake field inside the induction gap exited by the intense electron beam
linear induction accelerator induction gap wake field high voltage breakdown property
2009/8/17
While an intense electron beam passes through the accelerating gaps of a linear induction accelerator, a strong wake field will be excited. In this paper a relatively simple model is established based...
