Similarity laws predict the existence of direct-current
glow discharges at higher pressures. These scaling laws were developed
to study discharges in the low-pressure regime. It is therefore
worthwhile to revisit the theories developed for low-pressure discharges
and verify their applicability in the atmospheric pressure
domain. Similar discharges were investigated in a pressure range
of 200-1600 hPa using helium as operating gas. Under certain
conditions, a high degree of self-organization could be observed
on the anode. In this contribution, we present the trigger criteria
for these phenomena.
