1. A cooling system for a material surface treatment system, the cooling system comprising:
a plurality of conduits to convey a cooling fluid through an electrode, each conduit being connected to another conduit at one or more ends, wherein each conduit spans the length of a respective electrode, and a conduit of the plurality of conduits is connected to an electrical power source;
a voltage isolator disposed between the conduit and a reservoir, the voltage isolator configured to provide a pathway to a reference voltage for residual electric charge from the cooling fluid passing through the voltage isolator, wherein the voltage isolator comprises two or more tubes to convey the cooling fluid between the plurality of conduits and the reservoir;
a first port for introducing the cooling fluid into the two or more tubes; and
a second port for withdrawing the cooling fluid from the two or more tubes, wherein the first port is disposed in a first end of the plurality of conduits and the second port is disposed in a second end of the plurality of conduits, the cooling fluid to be conveyed through the length of the electrode.
