	In the 2015 Pb-Pb collision run of the LHC, the power of the secondary beams emitted from the interaction point by the bound-free pair production process reached new levels while the propensity of the bending magnets to quench is higher at the new magnetic field levels. This beam power is about 70 times greater than that contained in the luminosity debris and is focussed on a specific location. As long foreseen, orbit bumps were introduced in the dispersion suppressors around the highest luminosity experiments to mitigate the risk by displacing and spreading out these losses. An experiment designed to induce quenches and determine the quench levels and luminosity limit was carried out to assess the need for special collimators to intercept these secondary beams.

	A data analysis framework has been developed to perform systematic queries and automatic analysis of the large amount of data produced by the LHC beam loss monitoring system. The framework is used to provide continuous system supervision and can give advance warning of any potential system failures. It is also used to facilitate LHC beam loss analysis for determining the critical beam-abort threshold values. This paper describes the functionality of the framework and the results achieved from the analysis.

A data analysis framework has been developed to perform systematic queries and automatic analysis of the large amount of data produced by the LHC beam loss monitoring system. The framework is used to provide continuous system supervision and can give advance warning of any potential system failures. It is also used to facilitate LHC beam loss analysis for determining the critical beam-abort threshold values. This paper describes the functionality of the framework and the results achieved from the analysis.
