Ef­fi­cient ac­cel­er­a­tion and ma­nip­u­la­tion of high-bright­ness elec­tron beams using ter­a­hertz waves in a com­pact setup has been re­cently a hot re­search topic in ac­cel­er­a­tion com­mu­nity. Pre­vi­ous works have achieved multi-MV/m ac­cel­er­a­tion gra­di­ent and dozens of keV en­ergy gain while leav­ing room for fur­ther im­prove­ments in the high-en­ergy regime. Here, we ex­per­i­men­tally demon­strate whole-bunch ac­cel­er­a­tion and cas­caded ter­a­hertz-dri­ven ac­cel­er­a­tion of a rel­a­tivis­tic beam with a record en­ergy gain of 204 keV. A ter­a­hertz-dri­ven all-op­ti­cal elec­tron source is now under de­vel­op­ment, which hold great po­ten­tial for ter­a­hertz-dri­ven ul­tra­fast elec­tron dif­frac­tion and re­lated sci­en­tific dis­cov­er­ies.
