To un­der­stand the un­der­ly­ing com­plex beam di­ag­nos­tic often large num­bers of sin­gle-shot mea­sure­ments must be ac­quired con­tin­u­ously over a long time with ex­tremely high tem­po­ral res­o­lu­tion. Pho­tonic time-stretch is a mea­sure­ment method that is able to over­come speed lim­i­ta­tions of con- ven­tional dig­i­tiz­ers and en­able con­tin­u­ous ul­tra-fast sin­gle- shot ter­a­hertz spec­troscopy with re­fresh rates of tril­lions of con­sec­u­tive frames. In this con­tri­bu­tion, a novel ul­tra- fast data sam­pling sys­tem based on pho­tonic time-stretch is pre­sented and the per­for­mance is dis­cussed. THERESA (Ter­a­HErtz REad­out SAm­pling) is a data ac­qui­si­tion sys­tem based on the re­cent ZYNQ-RF­SoC fam­ily. THERESA has been de­vel­oped with an ana­log band­width up to 20 GHz and a sam­pling rate up to 90 GS/s. When com­bined with the pho­tonic time-stretch setup, the sys­tem will be able to sam­ple a THz sig­nal with an un­prece­dented frame rate of 8 TS/s. Con­tin­u­ous ac­qui­si­tion for long ob­ser­va­tion times will open up new pos­si­bil­i­ties in the de­tec­tion of rare events in ac­cel­er­a­tor physics.
