The design of the protection system for the superconducting elements in an accelerator such as the large Hadron collider (LHC), now under construction at CERN, requires a detailed understanding of the thermo-hydraulic and electrodynamic processes during a quench. A numerical program (SPQR ± simulati

In case of resistive transition of a LHC superconducting magnet ("quench"), the stored energy is dissipated in the winding within a few tenths of a second. A fraction of this energy is transferred to the helium inside the windings and around the beam tubes, causing expansion and axial flow. This res
This report demonstrates the role of quench back in the quench protection of high current density superconducting solenoid magnets with well-coupled shorted secondary circuits. The phenomenon of "quench back" can be used to greatly reduce the size of an external quench protection resistor or even to
This paper presents a study of the thermal eects on quench performance for several large Hadron collider (LHC) single aperture short dipole models. The analysis is based on the temperature pro®le in a superconducting magnet evaluated after a quench. Peak temperatures and temperature gradients in the
The quench protection by subdivision of the winding with use of the inter~l shunts for two solenoids was realized. The bores of the coils are 0.55 m and 0.7 m. Maximum stored energy is 0.15 MJ for the first coil, and it is 1.6 MJ for the another one. Heating of shunts and their effect on the tempera
