Temperature dependent parameters of stability and protection in an adiabatic niobium titanium coil

Experiments were performed to determine temperature-dependent parameters of stability and protection in a small adiabatic niobium titanium test magnet. Quench propagation velocity and minimum quench energy were measured as a function of operating temperature, transport current, and magnetic field. The operating temperature was controlled in an isothermal environment between 4.2 K and approximately 8 K. A computer code was modified to predict the magnet's behavior accurately within the temperature range. The aim was to develop improved analytical models of the effect of temperature parameters on stability in order to expand the understanding of the thermal behavior of adiabatic magnets operating at temperatures up to approximately 100 K.
