Description
The Large Hadron Collider (LHC) operates with 24 power converter circuits supplying the lattice skew quadrupole magnets for coupling correction. These circuits are currently not interlocked via the powering interlock controller (PIC). Recent operational experience shows that a trip of one of these circuits can cause relevant beam losses and lead to beam dumps via beam loss monitors.
This study employs Xsuite beam tracking simulations to assess the impact of individual skew quadrupole circuit failures on beam losses under realistic LHC Run 3 operating conditions. The simulations identify which circuits are proposed to be connected to the beam interlocking system during the 2025 Year-End Technical Stop.
