The hybrid magnet which consists of a 34T resistive inserts and an 11T superconducting outsert has been put into operation early this year at CHMFL. The superconducting outsert made of Nb3Sn CICC is cooled with forced flow supercritical helium at 4.5 K. The main helium cryogenic system includes a helium refrigerator and a helium distribution system for the cooling of superconducting coils,...

SBN Near Detector cryogenic system, planned to be commenced into operations at Fermilab in 2019, is being designed to match number of scientific and technical requirements. The poster provides background material to facilitate discussions of proposed operation modes and selection of equipment with specific emphasis of implementation “lessons learned” from operations of Fermilab LAPD, 35T and...

Toroidal field magnets of ITER cryogenic system contain over 7 ton of helium. Most of the inventory is expelled from the magnets n case of a quench and it needs to be captured in an external storage vessels (Quench Tanks). Force cooled technology with external gas circulation was chosen for these vessels in order to optimize their footprint and costs.

The future electron ion collider at Brookhaven National Lab consists of using one existing hadron ring and developing a new electron accelerator. This paper presents the cryogenic loads for the hadron ring’s superconducting ring and related upgrades to handle the additional loads. The cryogenic loads for the superconducting RF injector/accelerator and storage ring for the electron beam are...

The Circular Electron Positron Collider（CEPC）is a superconducting collider and it is currently under the conceptual design. CEPC will adopt 256 1.3 GHz 9-cell superconducting cavities in the booster ring and 384 650 MHz 2-cell cavities in the collider ring for the 120GeV beam energy. The superconducting cavities will operate at 2 K temperature. A large cryogenic system with the cooling...

Originally the spoke test cavity cryostat was designed to test exclusively SSR1 cavities. The goal of this upgrade is to extend this capability to SSR2 cavities, and to low and high beta 650 MHz cavities. These cavities are the last elements of the superconducting linac architecture which is the main component of the Proton Improvement Plan-II (PIP-II) at Fermilab.
The size of SSR2 and 650...
