ICS can ob­tain quasi-mono­chro­matic and di­rec­tional EUV ra­di­a­tion via a MeV-scale en­ergy elec­tron beam and a mi­cron-scale wave­length laser beam, which en­ables a dra­matic re­duc­tion in di­men­sion and ex­pense of the sys­tem, and makes it an at­trac­tive tech­nol­ogy in re­search, in­dus­try, med­i­cine and home­land se­cu­rity. Here we de­scribe an EUV source based on high rep­e­ti­tion ICS sys­tem. The scheme ex­ploits the out­put from the laser-elec­tron in­ter­ac­tion be­tween a MW-ps laser at MHz rep­e­ti­tion-rate and a high qual­ity elec­tron beam with an en­ergy of a few MeV at MHz rep­e­ti­tion-rate.

Cor­ru­gated and di­elec­tric struc­tures have been widely used for pro­duc­ing ac­cel­er­a­tor based ter­a­hertz ra­di­a­tion source. Re­cently, the novel schemes of the sub-ter­a­hertz free elec­tron laser (FEL) from a metal­lic wave­guide with cor­ru­gated walls and a nor­mal di­elec­tric loaded wave­guide dri­ven by a near-rel­a­tivis­tic (beam en­ergy of a few MeV) pi­cosec­ond elec­tron beam were stud­ied re­spec­tively. Such a beam is used for dri­ving res­o­nant modes in the wave­guide, and if the pipe is long enough, the in­ter­ac­tion of these modes with the co-prop­a­gat­ing elec­tron beam will re­sult in mi­cro-bunch­ing and the co­her­ent en­hance­ment of the wake­field ra­di­a­tion. It of­fers a promis­ing can­di­date for com­pact ac­cel­er­a­tor-based high power ter­a­hertz source which can be re­al­ized with rel­a­tively low en­ergy and low peak-cur­rent elec­tron beams. How­ever the choices of the wave­guide above is less ef­fec­tive in order to ob­tain high power with fre­quency around 1THz. In this paper, we pro­pose to use the wave­guide with a thin di­elec­tric layer in­stead, and high power ra­di­a­tion (>~10 MW) around 1 THz is ex­pected to ob­tain in the pro­posed struc­ture ac­cord­ing to the sim­u­la­tion re­sults.
