    　View Summary

    <p>We have developed a novel nonevaporable getter named oxygen-free Pd/Ti. After activation at 133℃, oxygen-free Pd/Ti evacuates H<sub>2</sub> and CO. Its pumping speeds do not decrease even after repeated cycles of activation and exposure to the air. Surface analysis by synchrotron radiation X-ray photoelectron spectroscopy showed that the carbon contamination decreased to an extent on heating in UHV, but decreased considerably on heating under an O<sub>2</sub> pressure. The partial pressures of H<sub>2</sub>, CO, H<sub>2</sub>O, and CH<sub>4</sub> in an oxygen-free-Pd/Ti coated chamber reduced to some degree after baking in UHV, but reduced remarkably after baking under an O<sub>2</sub> pressure (O<sub>2</sub> baking). Catalytic chemical reactions which remove carbon and hydrogen adsorbed on Pd surfaces appear to be responsible for the reduction of the partial pressures of H<sub>2</sub>, CO, H<sub>2</sub>O, and CH<sub>4</sub>. The pumping speeds of the oxygen-free Pd/Ti coated chamber for H<sub>2</sub> and CO improved remarkably after O<sub>2</sub> baking.</p>
