The effects of quench propagation are modeled in 40mm and 50mm diameter collider dipole magnet designs. This paper presents a comparative study of the cold diode (passive) and quench heater (active) protection schemes. The SSCQ modeling program accurately simulates the axial quench velocity and uses phenomenological time delays for turn-to-turn transverse propagation. The axial quench velocity is field dependent and consequently, each conductor's quench profile is tracked separately. No symmetry constraints are employed and the distribution of the temperatures along the conductor differs from the adiabatic approximation. A single magnet has a wide margin of self protection which suggests that passive protection schemes must be considered.
