PSI-XFEL and Elet­tra-Fer­mi-re­quire a X-band RF struc­ture. As CLIC is pur­su­ing a pro­gram for pro­duc­ing and test­ing x-band high-gra­di­ent RF struc­tures, a col­lab­o­ra­tion be­tween PSI, Elet­tra and CERN, has been es­tab­lished to build a mul­ti­pur­pose X-band ac­cel­er­at­ing struc­ture. This paper fo­cus­es on its en­gi­neer­ing de­sign which is based on disk-shaped cells bond­ed to­geth­er by dif­fer­ent tech­nolo­gies (dif­fu­sion bond­ing, vac­u­um braz­ing and laser beam weld­ing). The ac­cel­er­at­ing struc­ture con­sists of 2 cou­pler sub­assem­blies and 73 disks, and in­clude wake field mon­i­tor waveg­uides. The en­gi­neer­ing study also com­pris­es the ex­ter­nal cool­ing sys­tem, con­sist­ing of two par­al­lel cool­ing cir­cuits, and the tun­ing sys­tem, al­low­ing for the fine-tun­ing by means of cell de­for­ma­tions. The en­gi­neer­ing so­lu­tion for in­stal­la­tion and seal­ing of wake field mon­i­tor feed-through de­vices in­side the ac­cel­er­at­ing struc­ture RF-cav­i­ty is also pro­posed.
