A method of de­creas­ing the re­quired foot­print of lin­ear ac­cel­er­a­tors and im­prov­ing their en­ergy ef­fi­ciency is to em­ploy Di­elec­tric Disk Ac­cel­er­a­tors (DDAs) with short RF pulses ( ∼  9 ns). A DDA is an ac­cel­er­at­ing struc­ture that uti­lizes di­elec­tric disks to im­prove the shunt im­ped­ance. Two DDA struc­tures have been de­signed and tested at the Ar­gonne Wake­field Ac­cel­er­a­tor. A sin­gle cell clamped DDA struc­ture re­cently achieved an ac­cel­er­at­ing gra­di­ent of 1{02} MV/m. A multi-cell clamped DDA struc­ture has been de­signed and is being fab­ri­cated. Sim­u­la­tion re­sults for this new struc­ture show a 1{08} MV/m ac­cel­er­at­ing gra­di­ent with 400 MW of input power with a high shunt im­ped­ance and group ve­loc­ity. The en­gi­neer­ing de­sign has been im­proved from the sin­gle cell struc­ture to en­sure con­sis­tent clamp­ing over the en­tire struc­ture.
