Abstract

A pair of superconducting interaction region quadrupole magnets (SCQ) are used in the Beijing Electron-Positron Collider Upgrade (BEPCII). To avoid flow instabilities in constrained cooling channels, they are cooled by supercritical helium and independent cooling of each magnet is required. Hence, two throttle valves are used for each SCQ cooling system. A simple control strategy is theoretically verified in this paper. The analysis shows that the control strategy can meet all the operating requirements provided the proper parameters are chosen.
