SPQR – could it contribute?

Description

The thermal and electrical equations implemented in SPQR code are presented and possible improvements underlined. The approach used to numerically solve them is briefly recalled and the technique adopted to calculate the minimum quench energy (MQE) clarified. Examples of MQE calculations are presented for different space and time perturbations and the minimum propagation zone (MPZ) introduced. The sensitivity to helium cooling is discussed using the enthalpy approximation and more realistic models for heat transfer in He II are proposed. Strand stability versus multi-strand cable stability is addressed and the differences in realistic beam loss scenario are discussed. Finally ideas for future systematic studies of quench levels in the LHC superconducting magnets are proposed.
