The Elec­tron Ion Col­lider (EIC) to be con­structed at Brookhaven Na­tional Lab­o­ra­tory in the USA will be a com­plex sys­tem of ac­cel­er­a­tors pro­vid­ing high lu­mi­nos­ity, high po­lar­iza­tion, vari­able cen­ter of mass en­ergy col­li­sions be­tween elec­trons and pro­tons or ions. To achieve this a va­ri­ety of RF sys­tems are re­quired. They must pro­vide for cap­ture, for­ma­tion and stor­age of Am­pere-class beams in the elec­tron and hadron stor­age rings (ESR and HSR), fast ac­cel­er­a­tion of high-charge po­lar­ized elec­tron bunches in the rapid cy­cling syn­chro­tron (RCS), pro­vi­sion of cold high cur­rent elec­tron bunches in the high-en­ergy cooler ERL and pre­cise high-gra­di­ent crab­bing of elec­trons and hadrons ei­ther side of the in­ter­ac­tion point. The chal­lenges in­clude strong HOM damp­ing in the stor­age ring cav­i­ties and cooler ERL, very high fun­da­men­tal mode power in the ESR and cooler in­jec­tor, ex­tremely sta­ble low-noise op­er­a­tion of the crab cav­i­ties, mit­i­ga­tion of tran­sient beam load­ing from gaps, and op­er­at­ing over a wide range of en­er­gies and beam cur­rents. We de­scribe the high-level sys­tem pa­ra­me­ters and prin­ci­pal de­sign choices made and progress on the R&D plan to de­velop these state of the art sys­tems.

The de­sign of the elec­tron-ion col­lider EIC to be con­structed at Brookhaven Na­tional Lab­o­ra­tory has been con­tin­u­ously evolv­ing to­wards a re­al­is­tic and ro­bust de­sign that meets all the re­quire­ments set forth by the nu­clear physics com­mu­nity in the White Paper. Over the past year ac­tiv­i­ties have been fo­cused on ma­tur­ing the de­sign, and on de­vel­op­ing al­ter­na­tives to mit­i­gate risk. These in­clude im­prove­ments of the in­ter­ac­tion re­gion de­sign as well as mod­i­fi­ca­tions of the hadron ring vac­uum sys­tem to ac­com­mo­date the high av­er­age and peak beam cur­rents. Beam dy­nam­ics stud­ies have been per­formed to de­ter­mine and op­ti­mize the dy­namic aper­ture in the two col­lider rings and the beam-beam per­for­mance. We will pre­sent the EIC de­sign with a focus on re­cent de­vel­op­ments.
