EIC Estimated Energy Usage T. Satogata, JLab/ODU Thanks to C. Folz, R. Srinivasan, and T. Nehring (BNL) eeFACT 22 Workshop 12-16 September 2022
EIC Luminosity and RF, SR Power ~8.4-8.8 MW SR power Facility designed to max 10 MW ESR SR power Vacuum chamber, installed RF power ESR: 8-9 MW SR power at most operating points Installed ESR SRF power 13 MW 5 MeV 2.5 A beams => 0.5 MW SR power 2
EIC Cryogenic Power Location Power [MW] Central Plant (4K) 10.9 IR6 (Experiment) 0.32 SRF (2K) ERL (2K) IR10 (SRF) 0.56 IR2 (ERL cooler) 0.35 Total 12.1 These are based on CD-1 Conceptual Design Report That these numbers will likely change based on design updates to CD-2 e.g. ERL injector change to SRF e.g. IR6 magnet modification, spin rotator finalization Dominant 4K power well-known from RHIC operations and upgrade experience IR (2/4K) Central magnet refrigerator (4K) 3
