abstract = {We present discharge probability studies performed with a
single Thick Gas Electron Multiplier (THGEM) irradiated with
alpha particles in Ar-CO$_2$ and Ne-CO$_2$ mixtures. We
observe a clear dependency of the discharge stability on the
noble gas and quencher content pointing to lighter gases
being more stable against the development of streamer
discharges. A detailed comparison of the measurements with
Geant4 simulations allowed us to extract the critical charge
value leading to the formation of a spark in a THGEM hole,
which is found to be within the range of 3-7×10$^6$
electrons, depending on the gas mixture.Our experimental
findings are compared to previous GEM results. We show that
the discharge probability of THGEMs exceeds the one measured
with GEMs by orders of magnitude. This can be explained with
simple geometrical considerations, where primary ionization
is collected by a lower number of holes available in a THGEM
structure, reaching higher primary charge densities and thus
increasing the probability of a spark occurrence. However,
we show that the critical charge limits are similar for both
amplification structures.},
