Multiple harmonic generation is a key issue for coherence radiation generated by an electron beam modulated by the seeding laser. A new multiple harmonic generation scheme by combining the angular dispersion-induced microbunching (ADM) with the transverse echo effect, which can be easily generated by using pulsed dipoles, a pulsed quadrupole and a pulsed multipole, is investigated in a multi-bend achromatic storage ring. Simulation results demonstrate a triple of harmonic number compared to the case of pure ADM, making it possible to generate coherent extreme ultraviolet radiation in storage rings.
对于由种子激光调制电子束产生的相干辐射而言,多次谐波产生是一个关键问题。在多弯消色差储存环中,研究了一种新的多次谐波产生方案,该方案将角色散诱导微聚束(ADM)与横向回波效应相结合,利用脉冲偶极子、脉冲四极子和脉冲多极子可轻松产生这种效应。模拟结果表明,与纯ADM情况相比,谐波数增加了两倍,这使得在储存环中产生相干极紫外辐射成为可能。
