Quench Protection in Practice

The detection and energy-dump systems that keep a quenching magnet safe.

Method

Adiabatic hot-spot

Result

Self-protecting (design basis)

If a superconducting coil loses superconductivity, its stored energy must be removed before a local hot spot forms. Protection combines fast detection with a dump circuit that extracts the magnetic energy. Kronos analyses peak hot-spot temperature with an adiabatic method and reports the magnet as self-protecting within its design basis.

Quench protection is one of the validation items that is confirmed in-model rather than left open.
