Three superconducting technologies and related hardware systems need to be
developed:
• A pair of superconducting interaction region (SCQ) quadrupole magnets
• A pair of superconducting radio frequency (SRF) cavities
• A superconducting detector (SSM) solenoid magnet
• A cryoplant with a capacity of 1kW/4.5K (2x500W/4.5K refrigerator system)
Cryogenic system Cryogenic system is a big challenge: is a big challenge:
•• to serve for 3 types of SC device
• to adopt 3 types of cooling modes
• total capacity: 1kW/4.5K
• 2x500W/4.5K refrigerators
• based on conceptual design

Introduction
Task of BEPCII cryogenic systemTask of BEPCII cryogenic system• Production of cooling power (refrigerators)• Distribution of cryogen (valve boxes, transfer lines)• Preparation of cryogen (dewars, subcoolers)• Cooling of components (SCQ & SSM magnets, SRF cavities) • Variability and flexibility of refrigeration to handle different modes of operation• Process control & monitoring• Helium recovery and storage as liquid or gas(gas collection headers, tanks,
pressure vessels, leak tightness, closed circuit)• Helium purification (filters, separators, absorbers,driers, gas analyzers)• Handling of safety aspects(safety concepts, material certification, safety rules,
technical exam., pressure • Accommodation to collider buildings and tunnels

Introduction (1)
Cooling scheme for BEPCII SC deviceCooling scheme for BEPCII SC device• The cooling principles used to cool SC magnets are mainly determined by the temperature range of operation, heat loads, helium flow conditions, allowed pressure drops, spatial arrangement of the cold components and so on.• Supercritical helium cooling for SCQ magnets
Because the severe constrain in the radial dimension of the SCQ cryostat, the annular channels for LHe cooling flows are narrow. In order to eliminate the possible vapor bubble in the helium flow around the coil winding, the magnets are to be cooled by supercritical helium, even though the large latent heat cooling from the two-phase helium is attractive to reduce the budget of
cooling capacity of the cryoplant.
• Forced two-phase helium cooling for SSM magnet • Liquid helium cooling for SRF cavities
