making innovation happen, together

A variety of laboratory techniques and industrial systems require UHV or even XHV conditions to operate properly, such as:

•  Surface science and photoemission techniques such as AES (Auger Electron Spectroscopy), XPS (X-ray Photoemission Spectroscopy) or PEEM/LEEM (Photo Electron Emission Microscope/Low Energy Electron Microscope)
•  Atom trapping systems
•  Molecular beam epitaxy (MBE) equipment
•  Argon and Helium dating instrumentation
•  Mass spectrometers
•  Atomic clocks
•  Particle accelerators and large research vacuum experiments

Non-Evaporable Getter (NEG) technology was developed by Saes in the 70’s. Since  then  NEG pump and NEG solutions have  been increasingly adopted  by the  industry,  research  centers  and  large  physics  projects in all the above mentioned applications.

NEG solutions are generally used in combination with other pumps, such as sputter ion pumps, turbo-molecular or cryogenic pumps, to improve the ultimate achievable vacuum or to reduce the pumping time of the vacuum system.

NEG technology has also shown that it can provide significant contributions in mitigating baking conditions, allowing for example the achievement of the specified vacuum level with shorter bake-out cycles or using lower baking temperatures, thus increasing productivity and cutting energy costs.


Vacuum chambers, components and integrated systems, are now delivered through SAES-RIAL Vacuum S.r.l. a recently established company which combines RIAL Vacuum expertize in precision machining, design, welding and UHV testing with SAES experience in getter technology, material science and vacuum pumps. SAES -RIAL can supply state of the art vacuum chambers for accelerators, with or without NEG coating, and a variety of systems for accelerators, industrial process machines and cryogenics.
