Abstract
A getter device comprises a getter metal vapor releasing material and a source of an alkali metal which releases an alkali metal during or after the latter period of getter metal evaporation. Such getter devices are found to produce less methane after evaporation of the getter metal without producing higher hydrocarbons. A higher pressure of hydrogen is formed which aids cathode functioning.
