To pro­duce ra­di­a­tion in the THz fre­quency range at X-ray Free Elec­tron Lasers, un­du­la­tors with large pe­riod length, high fields, and large gaps are re­quired. These de­mands can be ful­filled by su­per­con­duct­ing un­du­la­tors. In this con­tri­bu­tion, the ac­tual re­quire­ments on the main pa­ra­me­ters of such a su­per­con­duct­ing un­du­la­tor will be dis­cussed and the progress of the de­sign will be dis­cussed. In ad­di­tion, beam im­ped­ance and heat load re­sults ob­tained an­a­lyt­i­cally as well as by large-scale wake­field sim­u­la­tions will be pre­sented.

  A 40-pe­riod su­per­con­duct­ing trans­verse gra­di­ent un­du­la­tor (TGU) has been de­signed and fab­ri­cated at Karl­sruhe In­sti­tute of Tech­nol­ogy (KIT). Com­bin­ing a TGU with a Laser Wake­field Ac­cel­er­a­tor (LWFA) is a po­ten­tial key for re­al­iz­ing an ex­tremely com­pact Free Elec­tron Laser (FEL) ra­di­a­tion source. The TGU scheme is a vi­able op­tion to com­pen­sate the chal­leng­ing prop­er­ties of the LWFA elec­tron beam in terms of beam di­ver­gence and en­ergy spread. In this con­tri­bu­tion, we re­port on the op­er­a­tional ex­pe­ri­ence of this TGU in­side its own cryo­stat and show the cur­rent sta­tus of the TGU and the fur­ther plan for ex­per­i­ments. This work is sup­ported by the BMBF pro­ject 05K19VKA Plas­maFEL (Fed­eral Min­istry of Ed­u­ca­tion and Re­search).
