    Abstract: A radiation source includes a fuel supply, a collector, a debris mitigation system, and a temperature control system. The fuel supply device supplies fuel. The excitation device excites the fuel into a plasma. The collector collects radiation emitted by the plasma and directs the radiation to a beam exit. The debris mitigation system collects debris generated by the plasma and has a first component having a first conduit passing therethrough and a second component having a second conduit passing therethrough. The temperature control system increases or decreases temperatures of the first component and the second component by selectively heating or cooling a thermal transfer fluid circulating through the respective conduit. The temperature control system cools the first component to a first temperature that is below the melting point of the fuel and heats the second component to a second temperature that is above the melting point of the fuel.
