Generation of wakefields by electromagnetic waves in a magnetized electron–positron–ion plasma

P K Shukla2009年Plasma Physics and Controlled FusionIF 2.2出版社

The generation of electrostatic wakefields by an ordinary mode radiation and a magnetic field-aligned circularly polarized electromagnetic (CPEM) wave in a magnetized electron–positron–ion (e–p–i) plasma is considered. It is found that the presence of the ions is essential for the generation of upper-hybrid wakefields by the ordinary mode radiation, while the magnetic field-aligned electron plasma wakefields are created by the ponderomotive force of CPEM only if either the ions or the external magnetic field is present in an e–p–i magnetoplasma. The electromagnetic wave generated wakefields can trap both the electrons and the positrons and accelerate them to very high energies.

磁化された電子-陽電子-イオン(e-p-i)プラズマにおける、常波モードおよび磁場に平行な円偏光電磁波(CPEM)による静電的航跡場の生成について考察する。イオンの存在が、常波モード放射による上部混成航跡場の生成に必須であることが見出された。一方、磁場に平行な電子プラズマ航跡場は、e-p-i磁化プラズマ中にイオンまたは外部磁場のいずれかが存在する場合にのみ、CPEMのポンデロモーティブ力によって生成される。電磁波によって生成された航跡場は、電子と陽電子の両方を捕捉し、それらを非常に高いエネルギーまで加速することができる。
