单能电子束在Laser等离子体加速器中的准直和加速

Collimation and acceleration of mono-energetic electron beams in Laser Plasma accelerators

Ravindra Kumar, V. Ravishankar

摘要:

基于等离子体加速器的快速发展,我们提出了一个简单的机制,用于生产高度准直的准单色电子束。通过考虑康普顿散射的电子(在等离子体中)与虚光子-通过一个有效的相互作用-我们证明角准直与发散小于3 mrad准单能性质的光束和能量增益为O(1 GeV/cm),在激光诱导加速器。

英文摘要:

Motivated by rapid advances in plasma based accelerators, we propose a simple mechanism for the production of highly collimated quasi monochromatic electrons beams. By considering Compton scattering of electrons (in the plasma) with virtual photons -- through an effective interaction --- we demonstrate angular collimation with a divergence less than 3 mrad quasi mono-energetic nature of the beam and an energy gain of O (1 GeV/cm), in laser induced accelerators.
