1. A plasma generation device for treating objects, the plasma generation device comprising:
a housing;
a plasma generation zone within the housing configured to enable accommodation of a first portion of an object while a second portion of the object is outside of the plasma generation zone;
a plasma generator for enabling formation of plasma within the plasma generation zone;
a plurality of vacuum pumps within the housing, each pump having a vacuum inlet;
a plurality of conduits within the housing connecting the plurality of vacuum pumps in series, such that when activated, the series of pumps cause a sub-atmospheric pressure within the plasma generation zone; and
at least one processor configured to simultaneously operate the plurality of vacuum pumps while the first portion of the object is in a region of the plasma generation zone.
 
11. A plasma generation device for treating objects, the plasma generation device comprising:
a housing;
a plasma generation zone within the housing configured to enable accommodation of at least a portion of an object, wherein the plasma generation zone is configured to enable accommodation of at least the portion of the object surrounded by a dielectric casing;
a plasma generator for enabling formation of plasma within the plasma generation zone;
a plurality of vacuum pumps within the housing, each pump having a vacuum inlet;
a plurality of conduits within the housing connecting the plurality of vacuum pumps in series, such that when activated, the series of pumps cause a sub-atmospheric pressure within the plasma generation zone; and
at least one processor configured to simultaneously operate the plurality of vacuum pumps while at least the portion of the object is in a region of the plasma generation zone.
