The possibility of plasma discharge initiation in the vicinity of an electrically insulated metal target occurring in plasma under the action of an incident flux of high-energy neutral particles is considered. Conditions for initiating discharge are determined and formulated as requirements on the incident flux parameters and plasma characteristics. The potential of a target, the electron concentration, and the electron current to the target surface in the presence of discharge are determined for an equilibrium state of the system.
