The Brookhaven Ac­cel­er­a­tor Test Fa­cil­ity (ATF) pi­o­neered the prin­ci­ples of Ac­cel­er­a­tor Stew­ard­ship and served the Ad­vanced Ac­cel­er­a­tor Con­cepts com­mu­nity as a users’ fa­cil­ity for over two decades. Over this time, the ATF pro­vided fa­cil­i­ties and ex­pert sup­port free of charge for users from acad­e­mia, in­dus­try and na­tional labs with a unique com­bi­na­tion of high-bright­ness elec­tron beams and high power lasers syn­chro­nized with the elec­tron beam as well as di­verse beam in­stru­men­ta­tion and con­trol soft­ware. There are over 30 sci­en­tists who did all or part of their grad­u­ate de­gree work using the ATF. The Ac­cel­er­a­tor Stew­ard­ship is now a for­mal pro­gram at the Of­fice of High En­ergy Physics (OHEP), and the ATF has been awarded a trans­for­ma­tional up­grade by OHEP, the ATF-II, that will lead in a short time to a dra­matic in­crease in the ca­pa­bil­i­ties of the fa­cil­ity. The Stew­ard­ship mis­sion and the ATF-II will be the sub­ject of this pre­sen­ta­tion.

Ra­di­a­Beam Sys­tems suc­cess­fully com­pleted test­ing of a proof-of-con­cept cor­ru­gated plate dechirper at the Brookhaven Na­tional Lab­o­ra­tory Ac­cel­er­a­tor Test Fa­cil­ity.* Such pas­sive de­vices should prove in­dis­pens­able for the ef­fi­cient op­er­a­tion of fu­ture XFEL fa­cil­i­ties. These ex­per­i­ments demon­strated a nar­row­ing of the en­ergy spec­trum in chirped beam bunches at 57.6 MeV. In this paper, we com­pare these re­sults with re­sults from El­e­gant sim­u­la­tions of the BNL-ATF beam. We also com­pare GdfidL sim­u­la­tions of the wake­field with the an­a­lytic re­sults of Bane and Stu­pakov.**
