    A Review of the Magnetic Forces in the CMS Magnet Yoke

    No full text
    A summary of the magnetic forces, acting on various ferromagnetic parts of the flux - return yoke of the CMS magnetic system is presented. The latest information about the parameters of the system has been taken into account: coil revision 5/98, yoke revision 6/98, hadronic forward calorimeter revision 6/98. The Vector Fields TOSCA code and the modified CERN POISCR code were used for two - and three - dimensional finite - element calculations of the magnetic field. The forces on ferromagnetic elements were computed using the Maxwell surface integral method. The obtained results are compared with the estimates of the magnetic forces presented in the Magnet Technical Design Report
