Estimation of thresholds for the signals of the BLMs around the LHC final focus triplet magnets

The Interaction Points of the Large Hadron Collider are the regions where the two circulating beams collide. Hence, the magnets closest to any Interaction Point are exposed to an elevated radiation field due to the collision debris. In this study the signal in the Beam Loss Monitors due to the debri...

description The Interaction Points of the Large Hadron Collider are the regions where the two circulating beams collide. Hence, the magnets closest to any Interaction Point are exposed to an elevated radiation field due to the collision debris. In this study the signal in the Beam Loss Monitors due to the debris is estimated and compared with the measurements. In addition, the energy density in the coils and the signal in the Beam Loss Monitors at quench are estimated for a beam loss scenario. It is shown that the Beam Loss Monitors, as presently installed on the vacuum vessel of the magnets, cannot disentangle the signal due to a localized loss from the constant signal due to the debris in case of steady-state losses.
