Due to the inherently transient behaviour of force cooled conductors there are no simple stability criteria. It is however possible to define a critical energy and to take it as a measure of stability. The critical energy is the minimum energy of a disturbance necessary to cause a quench of the cond

โฆ Synopsis
The two test conductors and the test facility SUL TAN are described. The critical energy has been measured as a function of disturbance length and duration, conductor current, background field, helium inlet temperature and pressure. The measured values are given and compared with those calculated numerically with the program L ONSA. An estimate of the accuracy of LONSA is made. For one series of measurements an approximate analytical calculation of the critical energy was made to show the different effects involved. Finally, a number of effects, which can lead to disturbances are briefly mentioned.

A numerical analysis of the thermal stability of a superconductor composite cooled by forced-flow supercritical helium has been performed. The analytical model consists of simultaneous two-dimensional coolant flow equations and a one-dimensional superconductor equation. The equations of conservation
He II (superfluid helium) is a unique fluid which offers substantial advantages when utilized as a coolant for large superconducting magnets. One of the principal advantages of He II is its extremely high heat conductivity which allows rapid diffusion of localized transient heating. The present pape
