Saes Getters

CapaciTorr® pumps use high porosity St172 sintered material and are particularly attractive in those applications where demanding performances have to be combined with compact package and best mechanical characteristics. The MK5 flange design results in a simple and compact overall pump assembly, with small foot print, small weight and intrinsic reliability. Pumps are available with several flanges, from CF 16 to CF 150, with pumping speed ranging from 20 to 3500 ls (H2). Highlights High pumping speed for all active gases High sorption capacity and increased lifetime Constant pumping speed in HV and UHV pressure regions Extremely compact design and low weight Operation at room temperature, after activation No interference with magnetic fields Oil free and vibration free operation

OLED and other advanced electronics materials are extremely sensitive to oxidizing agents and, especially, to moisture. This requires encapsulation materials with exceptionally high barrier properties. SAES active barriers sealants combine very low WVTR (Water Vapour Transmission Rate) with the getter function, in order to enable very long breakthrough times and an even more robust protection from the incoming flux of water. Our active barrier sealants portfolio is built upon the specific functional and process requirements of our customers. Besides the ZeoGlue®, eGloo and MicroSeal, a fully flexible active sealant (FlexGloo) completes the set of solutions for the encapsulation of curved, bendable, stretchable devices. Combining good barrier properties of a glassy epoxy system with an increased polymer chain mobility is not trivial and our R&D work has been addressed to the structure of the polymer backbone, the distribution of molecular weights, the glass transition temperature, the optimized dispersion of tailor-made getter particles: this made the FlexGloo a really valuable option for the emerging sector of the Plastic Electronics. SAES is also involved in improving TFE (Thin Film Encapsulation): please see the “Active Fillers” section for more details.

By leveraging the core competence in special metallurgy and industrial high volume production capabilities, SAES Group, as a Shape Memory Alloys (SMA) world leader supplier and manufacturer, offers a highly diversified product portfolio of SMA trained wires, springs and components, serving any need around industrial and medical applications.

SAES development of monochrome, color picture and display tube getters has been continuous for the last 70 years. Getter development began with the mass production of the stable barium-aluminum alloy (BaAl4), followed by the introduction of the ring-shaped exothermic and nitrogen-doped getters. The Frittable getters enabled the production of the first rectangular color cathode ray tube (CCRT) in the Sixties. With the advent of soft-flash technology, SAES Group’s R&D laboratories developed the high-wall, closed centre getter with wire supports for use in normal neck tubes, 20 mm in diameter, and in mini-neck tubes, 22.5 mm diameter.

High pumping speeds for all active gases. • Operation at moderate temperatures for HV applications with high gas loads. • Room temperature operation, in UHV systems, is also possible. • High sorption capacity and increased lifetime in the high vacuum regime. • Constant pumping speed in the HV and UHV-XHV pressure regions. • Compact design and low weight. • No interference with magnetic fields. • Oil free and vibration free operation. • Minimal power consumption during the operation (i.e., 5 – 50 W). Applications • Particle accelerators for basic research, medical and industrial applications. • Thin film deposition equipment in high vacuum. • Vacuum processing systems • Molecular beam epitaxy systems • General high vacuum system requiring fast pump downs, short down-time as well as large pumping speed and capacity for air and water. • SEM, TEM, FIB analytical systems.

NEG pumps have several unique characteristics which make them particularly attractive from high vacuum (HV) to ultra-extreme high vacuum (UHV-XHV). Main features are: • The highest pumping efficiency for hydrogen. • Pumping speed for active gases does not decline at low pressure. Pressure as low as 10-14 mbar has been obtained using NEG technology. • Very compact package, much more compact and lighter than any other type of pumps. • The highest pumping speed per unit pump volume, vacuum system miniaturization is possible. • Once activated they do not require power to operate. • Vibration-free, ideally suited for electron microscopes, semiconductor inspection tools or vibration-sensitive equipment and systems. • Negligible interaction with magnetic fields. • Pumping of selected heavy hydrocarbons and organics possible. • Large pumping speed and capacities also for air and H2O. Starting from January 2016 SAES Group can also deliver, through the participated company SAES-RIAL Vacuum S.r.l., a full range of state the art vacuum chambers, components and integrated systems for accelerators, industrial process machines or cryogenic devicesexperiments. NEG coating technology, which is fully mastered by SAES since 20 years can be integrated in narrow gap insertion device or accelerator vacuum chambers produced by SAES RIAL vacuum. SAES RIAL Vacuum group can therefore offer, as a single provider, the complete finished product, the NEG coated chamber.
