  This work reviews various methods used to minimize the probability of
discharge occurrence in MPGDs or to mitigate the effect of spark discharges on
the detector system. These include techniques that can reduce the probability
that the fundamental discharge limits of MPGD structures are reached during
detector operation, methods based on the HV scheme optimisation, or the
implementation of resistive electrodes to enhance local discharge quenching
capabilities in an amplification structure. In addition, design optimization
and quality control methods to ensure stable, long-term operation of an
MPGD-based detector, are considered.
