The presentation will cover first some theoretical and practical aspects of Non-Evaporable Getter (NEG) pumps technology, particularly efficient in pumping Hydrogen, the main gas species present at UHV levels. Then the NEX Torr pump concept will be introduced: the pump has been conceived as a combination of a NEG pump with a small Ion Pump, in order to provide performances better than conventional ion pumps in a smart miniaturized assembly several tens of times smaller and lighter. Examples of real use in a variety of cold trap systems as well as in other applications will be shown and discussed.
