Particle Accelerator

ZAO Non-Evaporable Getter (NEG) pumps and NEG coatings from SAES offer unmatched benefits for Particle Accelerator Systems, Large Vacuum Systems, and beamline components where Ultra-high Vacuum (UHV) and Extreme High Vacuum (XHV) conditions are essential.

Compared to conventional pumping technologies, ZAO NEG pumps stand out for their compact size, light weight, and extremely low magnetic permeability, making them ideal for particle accelerator vacuum chambers, RF cavities, collimators, mirror chambers, and other sensitive components. They generate no vibrations, consume no power during operation, and deliver outstanding pumping speed and capacity for hydrogen isotopes and active gases.

The sintered ZAO NEG solutions function as efficient process pumps during bake-out and pump-down phases, removing desorbed gases rapidly. Once optimal vacuum is reached, they maintain the UHV condition as stable standard NEG pumps, ensuring consistent system performance with minimal downtime.

Since 2015, SAES has expanded its offering to supply complete custom vacuum systems, integrating NEG pumping directly into vacuum chambers. This includes full design and production of vacuum chambers, selecting the ideal NEG pump configuration, conducting precise vacuum tests and cycle analyses, and supporting users with dedicated software for automated NEG reactivation—optimizing long-term performance for high-energy physics research facilities.
