Any upgrade of the Relativistic Heavy Ion Collider (RHIC) to an electron-ion collider (EIC) will involve large scale upgrades to the existing cryogenic infrastructure. The challenges to such a project at Brookhaven are unique because of the existing central cryogenic plant. The central plant is oversized for current RHIC operations and can handle the EIC’s heat loads comfortably. However, a lot of equipment will require 2 K cooling for which extra local cryogenic systems are needed. Any new systems will have to be designed to work in tandem with the existing RHIC cryogenic system. This places further constraints on the design of the system, with respect to the cryodistribution system. This study discusses the various baseline configurations for each local cryogenic system for the EIC upgrade.
