Coherent transition radiation in relativistic laser–solid interactions

C Bellei, J R Davies, P K Chauhan, Z Najmudin2012年Plasma Physics and Controlled FusionIF 2.2出版社

Coherent transition radiation (CTR) produced by the hot electrons generated when solid targets are irradiated by high-intensity lasers is examined. The theory is extended to include the effects of collisions on the generated hot electron beam. The collisional effects on electron transport, blooming and straggling, leads to transverse and longitudinal loss of coherence of the electron beam structure, resulting in a decrease in efficiency in the CTR. The directionality of the electrons leads to measurable non-radial components for the polarization of the CTR. With these effects accounted for, the properties of this radiation can give valuable information on the high-energy tail of the fast electrons produced at the target front side and transported through the solid-density material, such as temperature, direction and size of the filaments composing the beam.

コヒーレント遷移放射(CTR)は、高強度レーザーを固体ターゲットに照射した際に生成される高温電子によって発生するものであり、これを考察する。この理論は、生成された高温電子ビームに対する衝突効果の影響を含むように拡張される。電子輸送、ブルーミング、およびストラグリングに対する衝突効果は、電子ビーム構造の横方向および縦方向のコヒーレンス損失をもたらし、その結果CTRの効率が低下する。電子の方向性は、CTRの偏光において測定可能な非動径成分をもたらす。これらの効果を考慮に入れると、この放射の特性は、ターゲット前面で生成され固体密度物質中を輸送される高速電子の高エネルギー尾部に関する貴重な情報、例えば温度、方向、およびビームを構成するフィラメントのサイズなどを提供することができる。
