description The LHC design as from version 5 is equipped with tuning, trim and skew quadrupoles with similar cross-section designs (MQT). To qualify the quench detection and magnet protection needs, several compu tational methods have been applied. They range from global calculation of a uniform adiabatic temperature rise to more refined simulations, including the Quaber simulation package which is also applie d for quench calculations on the main magnets. A very important parameter is the quench propagation velocity, on which the Quaber simulations rely. An attempt was made to simulate the physics of the p ropagation itself, taking into account the temperature dependence of the wire parameters with the Quenchprop algorithm described in this report. The calculated results were compared with those from ex periments on a single wire. Further results of measurements on prototype magnets will allow fine-tuning of the program parameters.
