Reduction of outgassing<br />
Is essential for obtaining ultimate pressures<br />
1. Decreasing the H Concentration:<br />
-- Bakeout and high temperature bakeout (vacuum firing)<br />
2. Hindering H Desorption from the Surface:<br />
– Treatments to produce barrier layer on the surface: air bakeout<br />
– Passive coatings on the surface<br />
– Active coatings (NEG)<br />
