  In spite of the large di­men­sions of ac­cel­er­a­tors, like syn­chrotrons or col­lid­ers, the space avail­able for mount­ing UHV pumps is get­ting small­er, due to de­sign con­straints, ser­vice equip­ments, con­duc­tances, mag­nets, var­i­ous in­stru­men­ta­tions. This poses chal­lenges to tra­di­tion­al UHV pump de­signs which are called to pro­vide more pump­ing per­for­mances in small­er spaces. A rad­i­cal­ly new ap­proach is here pre­sent­ed which can mit­i­gate this issue. In this ap­proach Non Evap­orable Get­ter (NEG) and ion pump­ing tech­nolo­gies are prop­er­ly com­bined and in­te­grat­ed in one sin­gle de­vice, called NEX­Torr®, hav­ing a unique de­sign. In this pump, the get­ter car­tridge acts as the main UHV pump­ing el­e­ment, leav­ing to a small sput­ter ion pump the an­cil­lary task of re­mov­ing noble gases and methane, not pumped by the NEG. This de­sign al­lows achiev­ing large pump­ing speed in a very small pack­age as well as de­liv­er­ing in­ter­est­ing pump­ing syn­er­gies. Main fea­tures of this new pump, in­clud­ing pump­ing tests, and ex­am­ple of ap­pli­ca­tions will be re­port­ed, with a spe­cial focus to ac­cel­er­a­tors and high en­er­gy physics sys­tems. Its im­pact in the de­sign of vac­u­um sys­tems for ac­cel­er­a­tors will also be dis­cussed.
