Preliminary cryogenic loads requirements for the electron-ion collider at Brookhaven National Laboratory

摘要

The proposed electron ion collider at Brookhaven National Laboratory will consist of using one existing hadron ring and developing a new electron accelerator. This paper presents the cryogenic loads for the hadron ring's superconducting magnets as well as related upgrades to handle the additional loads. The cryogenic loads for the superconducting RF injector/accelerator and storage ring for the electron beam are summarized. The proposed cryogenic plant, and the configuration and flow distribution of the related cryogenic systems are also presented.
