Computational modelling of large aluminium stabilized conductors in an indirectly cooled magnet matrix
- Rutherford Appleton Lab., Chilton (United Kingdom)
Many of the detector magnets in use for Particle Physics experiments are based on a common technology developed in the 1980s: indirect cooling, pure aluminium stabilized conductor and monolithic resin impregnation (DELPHI, ALEPH, H1, TOPAZ etc.). In such indirectly cooled magnets stable behavior is a balance between the transient heat removal capacity of the winding and the thermal disturbances. For the extrapolation in magnet technology towards LHC detectors it is important to understand more fully this stability balance. This paper describes computational modelling techniques developed to predict the behavior of conductors in an indirectly cooled magnet matrix. The verification of the model is based on experimental studies of a test coil for the DELPHI solenoid. The computational model has been used to carry out a parametric study of the stability of the conductors proposed for the ATLAS End Cap Toroids at LHC. Results of the parametric study are presented.
