Sputter Ion Pump

Sputter ion pumps are one type of pump used to create ultra-high vacuum, and are used in many analyzers and accelerators.
ULVAC's acter pumps are designed for developing new elements (acter elements) with improved evacuation characteristics at ultra-high and extremely high vacuum, and to optimize magnetic fields.

Features

  • Ultimate pressure in the 10-9 Pa order (achieved with test dome complying with ISO standards)
  • Double the pumping performance achieved by the inert gas enhanced pumping model (type AU)
    (compared with the ULVAC's conventional pumps)
  • High pumping speed attained the ultra-high vacuum
  • Pumping down to ultra-high vacuum in a short period of time
  • Top-notch pumping characteristics in ultra and extremely-high vacuum (discharging maintained down to the ultra-high vacuum)

Applications

  • Accelerators
  • Electron microscopes
  • Analyzers
