ActiveUS20080047256A1Reduce erosionWeaken energyMachines/enginesOptical signallingIon bombardmentHigh pressure
A gas-fed hollow cathode keeper can reduce ion bombardment erosion by expelling gas through the keeper faceplate. The expelled gas effectively creates a high-pressure “shield” around the keeper such that bombarding ions suffer energy-reducing collisions before impacting the keeper. If the bombarding ion energy is reduced enough, the erosion is eliminated since sputtering is a threshold phenomenon.
