    摘要: 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.

    摘要: A process is provided for production of a refrigerating circuit comprising non-evaporable getter material, wherein said getter material, previously introduced into the same circuit, is heated to a temperature of at least 200° C. during or immediately after the circuit evacuating step, at a residual atmospheric gas pressure of not less than 10 mbar, before introduction of the mixture of cooling fluids and before the circuit sealing. Preferred is the use of zirconium-based getter alloys.
