Description
An accurate prediction of the quench levels of the main ring superconducting magnets
will allow a preventive dump of the beam before the magnet quench based on beam loss
measurements with beam loss monitors, thus limiting the downtime of the machine. The
particle energy deposition in the coils is calculated by using simulation programs
like GEANT or FLUKA. The magnet quench level as a function of proton loss
distribution and magnet specific parameters can be estimated using codes like SPQR
and ROXIE. Until now simplified analytical calculations have been done for the main
dipole magnets. In this presentation the current knowledge of the quench levels of
various families of the main ring superconducting magnets will be addressed, taking
into account experience from other colliders and from magnet tests at CERN. An
outlook on further simulations for the quench levels and envisaged experiments to
validate the simulations will be discussed.
