In an ongoing effort to understand stability and quench characteristics in large high field superconductivity systems, a series of Quench Initiation and Propagation Studies (QUIPS) is being employed. The goal is to establish a database of stability and quench information for the present 45 T Hybrid project and for future applications. To reach the goal in an efficient, cost effective manner, novel techniques are implemented to model high field stability and quench behaviour in cable in conduit conductors (CICC) at relatively low fields. A relatively low J/sub c/ superconductor having a comparable critical temperature is used to approach the operating temperature margins of the Nb/sub 3/Sn conductor in the A subcoil of the 45 T Hybrid. One particular technique was the heat treatment of the single triplex NbTi CICC to degrade the J/sub c/ for stability matching purposes. Design parameters and operating conditions of the long solenoid are also tailored for optimal sealing. This paper discusses the analytical methods, processes, and their associated effects on the model.
