Title: Computer program simulating the quench of superconducting magnet systems

Abstract

A computer program for testing coil and protection design of a composed magnet system is presented. Small high field magnets composed of two uniaxial cylindrical oils of different superconducting materials (e.g., NbTi and V/sub 3/Ga or Nb/sub 3/Sn) are considered. Each coil consists of several sections protected by shunts. The system is driven by one power supply. In order to take into account quench propagation due to thermal conduction and to rapid current increase, which is important in inductively coupled systems, a one-dimensional thermodiffusion equation is solved. Field and temperature dependence of the critical current of every layer of the magnet system are regarded. Current sharing as well as the temperature dependence of specific heat, of resistivity and of thermal conductivity are taken into account. 8 refs.

  • A computer program QUENCH-M applicable to the quench analysis of various superconducting magnet systems has been developed. The program was applied to some typical systems. This paper concentrated on the circuit calculation of quench analysis for superconducting magnet systems. The graphical outputs of voltage and temperature distributions within superconducting coils were shown to be very useful for understanding the quench process. This program was found very useful for estimation of the maximum voltage during quench, because the maximum voltage is not estimated only from the resistance of the normal zone, but also from the voltage distribution within the coil.
  • For the detailed analysis of the propagation of normal conducting zones in forced flow cooled superconducting coils the code system MAGS has been developed at Kernforschungszentrum Karlsruhe. The code system is modular, i.e., depending on the desired degree of details of the results the user can choose between different modules and options to adjust the analysis effort to the requirements. The paper gives a rough description of the modules. An example for application is the analysis of a quench in an ITER coil using a detailed and a coarse model. It turned out that the coarse model gives results withmore » an error of 50% in peak temperature compared to the detailed results. Keeping in mind that the computing effort is reduced with the coarse model by two orders of magnitude the coarse model is an interesting option of MAGS.« less
  • Ontario Hydro has developed a computer program called FLOSHEET for simulation of hydrogen isotope and fusion fuel processing systems. The development of the program was initiated to provide support for the commissioning and operation of the Darlington Tritium Removal Facility (DTRF) at Ontario Hydro's Nuclear Generating Station A. The program has also proven useful in simulating tritium systems in fusion applications. FLOSHEET has been developed as a general purpose simulator which can be used to simulate many different types of processors and process flowsheets. This paper describes the FLOSHEET process simulator and its application to the DTRF and fusion reactormore » tritium systems.« less
  • In this paper, the quench dynamic characteristics in an epoxy impregnated superconducting magnet are investigated in both experimental and simulation studies. The quench is induced by a ring heater located at the inside of the magnet midplane. The longitudinal and transverse propagation velocity calculations, using conventional formula, enable the authors to simulate the quench phenomena two dimensionally. Good agreement is obtained between simulated and experimental results. By separating the resistive voltage components from the simulated voltage tap signals, it is possible to calculate a transverse quench propagation velocity, which agrees with calculated results.
  • In this paper the results of helium thermal-hydraulic transients modeling of the UNK superconducting magnet system are presented. The model is based on the set of one-dimensional mass, energy and momentum conservation equations for helium flow in the cooling channels and heat conduction equation for the wall, subjected to appropriate boundary and initial conditions. The mass and energy transfer between helium in the winding gaps and helium flowing in the cooling channels is taken into account. Pressure, temperature and helium mass flow developments during a quench in the quench protection unit magnets and in the header were calculated. The influencemore » of heat and mass transfer between helium trapped within winding gaps and helium stream on pressure behavior in magnet is analyzed. It has been found that the amount of liquid helium contained in the winding affects maximum quench pressure. The computer code developed could be used for further analysis of thermal-hydraulic processes in the superconducting magnet systems cooled by single-phase and supercritical helium flow.« less
