“…The strategy to realize this goal involves the micro-β y scheme and the multi-bunch collision, which is implemented by two superconducting RF (SRF) cavities [2] and a pair of superconducting quadrupole (SCQ) magnets [3] in the double-ring of BEPC . For the BES (Beijing Spectrometer ) detector the superconducting solenoid magnet (SSM) is adopted to produce an axial magnetic field of about 1.0 T with good field uniformity over the tracking volume [4] . Dedicated for cooling the three kinds of superconducting devices, which have respectively distinct requirements in the cooling principles, a cryogenic system with a total capacity of 2×0.5 kW at 4.5 K has been built at IHEP in the framework of the collaboration between the Technical Institute of Physics and Chemistry (TIPC) and IHEP, Chinese Academy of Sciences (CAS).…”

The cryogenic system of the upgrade project of Beijing Electron Position Collider (BEPCII) is being built at Institute of High Energy Physics (IHEP). The system has a total capacity of 1.0 kW at 4.5 K for cooling three kinds of superconducting devices, superconducting RF (SRF) cavities, superconducting quadrupole (SCQ) magnets and the superconducting solenoid magnet (SSM). Two sets of refrigerators, each with a capacity of 500 W at 4.5 K are adopted. In order to prepare for the commissioning of the cryogenic system, the refrigeration process was simulated and analyzed numerically. The simulation was conducted based on the latest engineering progresses and focusing on the steady state operation mode. The simulation results, such as the helium mass flow rates and pressure drops over the control valves of different cooling channels, thermodynamic parameters of each superconducting device, etc., are presented in this paper. When considering the heat loads, the powers of heaters of each device were figured out to realize the nominal operation modes.
