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.
