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.
