We introduce a on-parameter family of SU(N) gauge actions which, when used in combination with an HMC update algorithm, prevent the gauge system from entering an artificial bulk-"phase". We briefly discuss the (presumed) mechanism behind the bulk-prevention and present test results for different SU(N) gauge groups.
