โœฆ Synopsis

The stability of a specific forced convection cooled conductor is analysed with two dynamic models of different complexity. We compare the dynamic analysis with static criteria. First we introduce a dynamic model of the conductor where the coolant is modelled as a constant temperature bath. A constant heat transfer coefficient is assumed. We found a critical energy that is not a function of the disturbed length for small sizes, and is proportional to the disturbed length for larger sizes, To introduce transient effects in the helium flow we solved a two dimensional flow and thermal model of the coolant. We present some characteristics of the transient behaviour. Critical energy appears to increase from 4 mJ to 15 mJ when transient effects are considered.

A simple qualitative model is proposed to explain the fast initial change of the magnetic field of superconducting magnets which operate in the persistent mode. Using this model the additional component of the transport current which is induced by the decaying screening currents can be represented.

The flux jump stability characteristics of an edge-cooled tape superconductor are analysed. Two simple cases (no stabilizer, perfect stabilizer) are considered to establish the lower and upper bounds of the stable operating space. The generalized case is then solved in the interesting limit where th
